Trust in the LORD with all thine heart; and lean not unto thine own understanding. (Proverbs 3:5) *1/ Why we should trust in the LORD. 2/ Why we should **not** lean to our own understanding. 3/ What are we to trust him for and how is that trust evidenced?* *This sermon was preached via Zoom to Providence Chapel Northampton.* **Sermon Summary:** The sermon centers on the imperative to trust God completely, as commanded in Proverbs 3:5, emphasizing that true faith involves trusting in the LORD with all our heart, rejecting self-reliance in favour of divine sovereignty. It argues that God is worthy of trust because of His eternal purpose, infinite knowledge, sovereign power, and unchanging love, all of which are demonstrated throughout Scripture—from the covenant with Abraham to the redemptive plan fulfilled in Christ. The sermon warns against relying on human understanding, which is limited, fallible, and prone to deception, using examples like the Gibeonites and the Israelites' misjudgement to illustrate the dangers of self-trust. Ultimately, genuine trust is evidenced not in passive resignation but in active obedience: seeking salvation through Christ, pursuing spiritual growth, engaging in prayer and the means of grace, and making decisions aligned with Scripture, providence, and a willing heart, all while relying on God's guidance in every area of life.
