Rosebank Union Church Sermons

Romans 10:5–17 is Paul’s passionate reminder that salvation is not achieved by human effort but received through faith in Jesus Christ. The gospel is wonderfully accessible—“the word is near you”—and anyone who believes in their heart and confesses Jesus as Lord will be saved. Paul then asks a series of urgent questions: How can people call on Christ if they haven’t believed? How can they believe if they’ve never heard? And how can they hear unless someone tells them? He concludes with this powerful truth: “Faith comes from hearing the message.”This message speaks directly into the mission of Campus Outreach South Africa, serving students at Wits and UJ. University campuses are full of young adults searching for meaning, identity, direction, and hope. Paul’s words remind us that students won’t encounter the life-changing message of Christ unless someone brings it to them. This is why Campus Outreach places staff and student leaders in the “harvest field” of the campus—building relationships, sharing their lives, and clearly proclaiming the gospel so that students can hear, believe, and be transformed.Faith begins with hearing the gospel, and hearing requires messengers. God calls us—just like Campus Outreach—to step onto our campuses, workplaces, and communities so that others may hear the good news and find eternal life in Christ.~~~Plan a visit to Rosebank Union Church in Sandton, Johannesburghttps://ruc.org.za/visit

In this passage, Paul reminds believers that God calls each person to serve Him right where they are. Whether Jew or Gentile, slave or free, circumcised or uncircumcised—our value and purpose come not from our status, background, or circumstances, but from belonging to Christ. Paul urges the church not to chase identity in social change or comparison, but to live faithfully in the place where God has positioned them, using what they have for His glory and the good of others.This truth speaks directly into the work of Rays of Hope in Alexandra Township. God is at work through ordinary people in ordinary places, transforming lives through consistent presence, dignity, and love. Rays of Hope doesn’t wait for “perfect conditions” or “ideal circumstances”—it steps into real communities with real challenges and reflects Christ’s heart by empowering, uplifting, and walking alongside families and children right where they are.God places us intentionally. When we serve faithfully in the context He has given us—whether in Alexandra or in our own neighbourhoods—He turns everyday obedience into Kingdom impact.~~~Plan a visit to Rosebank Union Church in Sandton, Johannesburghttps://ruc.org.za/visit

In this passage, Jesus meets people in two powerful moments — first, healing a paralysed man brought by friends who refused to let barriers stop them, and then calling Levi (Matthew), a tax collector, to follow Him. Both stories reveal Jesus’ heart for the broken, the excluded, and the searching. He forgives sins, restores dignity, and reminds the self-righteous that “It is not the healthy who need a doctor, but the sick.”Like the friends who carried the paralysed man and like Jesus reaching out to Levi, Red Frogs volunteers are called to meet people where they are—in the middle of the party, the chaos, or the confusion—and bring them hope, safety, and love. This is what it means to live out the gospel: to be the hands and feet of Jesus to those who may not step into a church, but still need to encounter His grace.Jesus meets people in their mess, not their perfection. Through acts of care and compassion, like Red Frogs’ mission, we carry others to Him—showing that His love is strongest where it’s needed most.~~~Plan a visit to Rosebank Union Church in Sandton, Johannesburghttps://ruc.org.za/visit

In this passage, Jesus calls His first disciples. After teaching from Simon Peter’s boat, Jesus tells him to cast his nets again, even after a fruitless night of fishing. Peter obeys—and the nets overflow with fish. Overwhelmed, Peter falls before Jesus, confessing his unworthiness. But Jesus lifts him up with a new purpose: “Do not be afraid; from now on you will catch men.”This moment reveals Jesus’ power, Peter’s humility, and God’s grace in calling ordinary people to extraordinary purpose. The disciples leave everything to follow Him, showing that true faith responds in obedience and surrender.When we trust and obey Jesus, even against our understanding, He transforms our emptiness into abundance and calls us to a greater purpose in His kingdom.~~~Plan a visit to Rosebank Union Church in Sandton, Johannesburghttps://ruc.org.za/visit

In this third episode of Sidebar Zwai, Richard, and Ansune dive into the sobering yet hopeful prophecy of Isaiah 24. A chapter that paints a picture of global judgment and ultimate renewal. They explore the theme of the earth’s curse due to human rebellion, the inescapable judgment awaiting both earthly rulers and spiritual powers, and the glorious promise of a new heaven and a new earth. Drawing connections to Revelation 21–22 and 2 Peter 3, they emphasize that God’s final act is not destruction, but redemption; remaking all things through Christ, the true Curse-Breaker. This is a message of warning, but also of deep hope for those who long for the day when creation is finally set free.~~~Recommended Resources:-The Supreme Malediction by RC Sproulhttps://www.renewingyourmind.org/2021/04/01/the-supreme-malediction-The Bible Project content on "New Creation" and "Judgment" for example:https://bibleproject.com/podcasts/heaven-hell-3-divine-judgment-and-resurrection-hope/https://bibleproject.com/articles/new-heaven-new-earth/

Isaiah 25 is a song of praise celebrating God’s victory and faithfulness. After the judgments of the previous chapter, Isaiah rejoices that God has humbled the proud and protected the poor and needy. The Lord is pictured as a refuge in the storm and a shelter from the heat. On His holy mountain, God prepares a great feast for all nations, destroys the shroud of death, and wipes away every tear.This passage beautifully points to God’s ultimate plan of salvation and eternal joy for His people. It reminds us that even through seasons of judgment and sorrow, God is working toward redemption and restoration.God turns mourning into celebration—He destroys death and brings everlasting joy. Our hope and praise belong to the Lord, who is our refuge, Redeemer, and eternal King.~~~Catch the Season 1 of Isaiah Recap video: https://youtu.be/060uJTJZwLY~~~Get more information on the series:https://ruc.org.za/isaiahPlan a visit to Rosebank Union Church in Sandton, Johannesburghttps://ruc.org.za/visit

Isaiah 24 presents a sweeping vision of God’s judgment over the whole earth. The Lord brings devastation because humanity has broken His covenant and defiled the land with sin. Joy fades, cities crumble, and the proud are brought low. Yet in the midst of destruction, a faithful remnant lifts their voices in praise, declaring God’s glory among the nations.This chapter reveals both the seriousness of sin and the certainty of God’s justice—but also the hope that remains for those who trust in Him. Even when the world shakes, God remains King, reigning in righteousness and faithfulness forever.God’s judgment is real and universal, but His glory and salvation endure. When everything else falls, those who trust in the Lord will stand firm and rejoice in His unshakable kingdom.~~~Catch the Season 1 of Isaiah Recap video: https://youtu.be/060uJTJZwLY~~~Get more information on the series:https://ruc.org.za/isaiahPlan a visit to Rosebank Union Church in Sandton, Johannesburghttps://ruc.org.za/visit

In this episode, Zwai and Ansuné chat about how we can approach interruptions and disruptions from a biblical perspective.

Isaiah 23 prophesies the downfall of Tyre, a wealthy and powerful trading city. Its merchants and sailors are left mourning as the Lord brings judgment on its pride and materialism. Tyre’s strength and riches, which once seemed unshakable, are shown to be temporary under God’s sovereign hand. Yet after seventy years, God promises to restore Tyre—but this time its wealth will serve the Lord, not human greed.This chapter reminds us that worldly success and wealth can easily become idols if they draw our hearts away from God. But when surrendered to Him, even material blessings can be used for His glory and kingdom purposes.Earthly riches and power are fleeting, but God’s rule is eternal. True prosperity is found when we use what we have to honor and serve the Lord.~~~Catch the Season 1 of Isaiah Recap video: https://youtu.be/060uJTJZwLY~~~Get more information on the series:https://ruc.org.za/isaiahPlan a visit to Rosebank Union Church in Sandton, Johannesburghttps://ruc.org.za/visit

Welcome back to Sidebar from Rosebank Union Church — where we go deeper into Scripture beyond the Sunday sermon. In this second episode, Zwai, Richard, and Ansuné unpack the dramatic story of Shebna and Eliakim in Isaiah 22. An interlude between prophecies against Jerusalem. Why does God interrupt His oracle to focus on two royal officials? What does it mean to be a true steward of divine authority? We explore: -The arrogance of Shebna, who builds a grand tomb for himself while the city faces crisis-The elevation of Eliakim, clothed with authority and called “a father” to the people-The powerful metaphor of “a peg in a sure place” — and how it points forward to Christ-Connections to Christmas, the throne of David, and Jesus’ promise: “I will place on his shoulder the key of the house of David” (Isaiah 22:22; Revelation 3:7)Key Passages:Isaiah 22:1–25 | 2 Kings 18:18–37 | Isaiah 9:6 | Revelation 3:7~~~Recommended Resources:-Preaching the Cross by Mark Deverhttps://www.amazon.com/Preaching-Cross-Mark-Dever/dp/1581348282-The Unfolding Message of the Bible by G.

Isaiah 22 delivers a message of judgment on Jerusalem. Instead of humbling themselves before God in a time of crisis, the people chose denial and self-indulgence—saying, “Let us eat and drink, for tomorrow we die.” The chapter also warns against misplaced trust in human leaders, using Shebna (the proud steward) as an example, and contrasts him with Eliakim, who is established by God as a faithful servant.This passage reminds us that when trouble comes, God calls us to repentance and reliance on Him—not to escape into pleasure or to depend on human strength. True security and leadership are found only in the Lord’s chosen one.In times of crisis, God calls us to repentance and trust in Him. Pride and self-reliance lead to downfall, but those who humble themselves under God’s authority will stand firm.~~~Catch the Season 1 of Isaiah Recap video: Recap Video~~~Get more information on the series:https://ruc.org.za/isaiahPlan a visit to Rosebank Union Church in Sandton, Johannesburghttps://ruc.org.za/visit

Isaiah 21 contains oracles against Babylon, Edom, and Arabia. Babylon, the great empire, is pictured as falling suddenly under God’s judgment, showing that no worldly power is secure against His hand. Edom is warned of a time of distress with only brief relief, while Arabia faces hardship and scattering.Through these prophecies, Isaiah highlights the certainty of God’s word: what He declares will surely come to pass. The mighty are humbled, the proud are shaken, and the nations are reminded that their strength cannot stand before the Lord.God’s word never fails—nations rise and fall, but the Lord’s purposes stand firm. Our security is not in human power, but in trusting the God who rules history.~~~Catch the Season 1 of Isaiah Recap video: Recap Video~~~Get more information on the series:https://ruc.org.za/isaiahPlan a visit to Rosebank Union Church in Sandton, Johannesburghttps://ruc.org.za/visit

Isaiah 19 declares judgment on Egypt: its idols will tremble, its wisdom will fail, and its economy and leadership will collapse. Yet, the chapter also ends with a surprising vision of hope—Egypt, Assyria, and Israel united in worship of the Lord, showing God’s plan to redeem even former enemies.Isaiah 20 then gives a vivid sign-act: Isaiah walks barefoot and stripped of outer garments for three years, symbolizing how Egypt and Cush will be led away in shame by Assyria. This was a warning to Judah not to trust in foreign powers for protection, but to rely on God alone.Together, these chapters teach that nations that exalt themselves or trust in idols will fall, but God’s ultimate purpose is to bring salvation and unity among all peoples.Trusting in human power leads to shame, but God’s plan brings down pride and opens the way for redemption and peace through Him alone.~~~Catch the Season 1 of Isaiah Recap video: Recap Video~~~Get more information on the series:https://ruc.org.za/isaiahPlan a visit to Rosebank Union Church in Sandton, Johannesburghttps://ruc.org.za/visit

Justin speaks through some of his favoured scripture as he reflects on lessons learned and changes he has weathered throughout his life and career, as well as the effect that they have had in shaping him.

In Isaiah 17, God pronounces judgment on Damascus and Israel. Once proud and flourishing, they will be reduced to ruin because they trusted in idols and foreign alliances instead of the Lord. Yet, even in judgment, there is a glimpse of hope: a remnant will turn back to God, remembering their Maker.Isaiah 18 speaks to Cush (Ethiopia), portraying a nation of power and influence. Though Cush sends envoys and displays strength, God reminds them that He is the one who directs the course of nations. At the appointed time, all nations will recognize His sovereignty and bring tribute to the Lord in Zion.Together, these chapters remind us that human strength, wealth, or alliances cannot save—only God can. Judgment is certain for the proud and the self-reliant, but those who return to the Lord will find mercy and life.Earthly power cannot secure us, but turning back to God does. Nations rise and fall, but the Lord remains sovereign over all.~~~Catch the Season 1 of Isaiah Recap video: Recap Video~~~Get more information on the series:https://ruc.org.za/isaiahPlan a visit to Rosebank Union Church in Sandton, Johannesburghttps://ruc.org.za/visit

In the oracle against Moab, Isaiah delivers a prophecy of judgment against Moab. The cities of Moab are pictured in ruins, and its people are filled with grief, weeping, and fleeing for survival. Yet in the midst of judgment, there is a call for Moab to seek refuge in Zion and to show kindness to God’s people. Ultimately, Moab’s pride leads to its downfall, and within three years the nation is humbled and broken.This passage highlights both God’s justice against sin and His offer of mercy to those who turn to Him. The contrast is clear: pride brings destruction, but those who humble themselves and seek the Lord find hope and security.Pride leads to ruin, but God offers mercy to those who take refuge in Him. Our safety and future are not in our own strength, but in trusting the Lord’s reign.~~~Catch the Season 1 of Isaiah Recap video: Recap Video~~~Get more information on the series:https://ruc.org.za/isaiahPlan a visit to Rosebank Union Church in Sandton, Johannesburghttps://ruc.org.za/visit

Welcome to the Sidebar — a new podcast where we go deeper into Scripture beyond the Sunday sermon. In this episode, hosts Zwai Zulu, Ansune Schoeman, and Richard van Lieshout unpack the poetic taunt in Isaiah 14 and explore a compelling question: Is this passage only about the king of Babylon — or is there a deeper, spiritual reality at play? We journey from Genesis 10–11 through Isaiah, Daniel, and the New Testament, connecting biblical dots to reveal how the origin of Babylon — founded by Nimrod — is entwined with ancient spiritual rebellion. Could the pride of the Babylonian king mirror the fall of a heavenly being? We examine the Nephilim, the "sons of God," the meaning of Rephaim, and how ancient language points to a cosmic battle behind human tyranny. ~~~Recommended Resources:-The Bible Project – “Spiritual Beings” serieshttps://bibleproject.com/videos/collections/spiritual-beings/-Word Matters – Episode on Genesis 6https://wordmatterspod.csbible.com/2016/08/08/episode-19-who-were-the-nephilim-Expositional Leadershiphttps://www.crossway.org/books/expositional-leadership-ebook/-The God Who Is There by D.A.

Isaiah 14 continues with God’s promise to restore His people and bring judgment on their oppressors. The chapter opens with comfort: the Lord will have compassion on Israel, gather them back, and give them rest from sorrow and fear. In contrast, Babylon—the symbol of pride and arrogance—will be brought low. The once-mighty oppressor is mocked, shown as powerless in death, and humbled before the Lord of hosts. This passage reminds us that no kingdom, leader, or force that exalts itself against God can endure. Human pride ends in downfall, but God’s people find hope and strength in His faithfulness. The proud are brought low, but the Lord gives His people rest and a future. True security is not in earthly power, but in the God who rules over all nations.~~~Catch the Season 1 of Isaiah Recap video: Recap Video~~~Get more information on the series:https://ruc.org.za/isaiahPlan a visit to Rosebank Union Church in Sandton, Johannesburghttps://ruc.org.za/visit

In this passage, God delivers a prophecy against Babylon, announcing its coming judgment for pride, cruelty, and idolatry. Through Isaiah, the Lord declares that He will stir up nations to bring Babylon down, leaving it desolate and without mercy for those who oppressed His people. The fall of Babylon is not only a historical event but also a reminder that no earthly power, no matter how mighty, can stand against God’s sovereignty.For God’s people, this judgment is also a promise of deliverance. Those who were once captives will be set free, returning to their land and finding rest in the Lord’s justice. This reminds us that God sees the suffering of His people, and at the right time, He will act to rescue them and humble the proud.God’s justice is sure, His power unmatched, and His care for His people unfailing. We can trust Him to bring down the proud and lift up the humble in His perfect timing.~~~Catch the Season 1 of Isaiah Recap video: Recap Video~~~Get more information on the series:https://ruc.org.za/isaiahPlan a visit to Rosebank Union Church in Sandton, Johannesburghttps://ruc.org.za/visit
