The sermon presents Revelation as a message of hope and endurance, centered on the sovereign, self-existent God who is 'the Alpha and the Omega, who is and who was and who is to come.' It emphasizes that the book's primary call is not to speculate about end times, but to 'keep' its words—guard and trust them—especially in suffering. Through the vision of Christ as the faithful witness, firstborn from the dead, and ruler of kings, the preacher affirms Christ's victory over evil and His ultimate authority over all earthly powers, offering comfort to believers facing persecution. The passage also highlights the believer's identity as a 'kingdom of priests'—a royal, priestly people redeemed by Christ's blood and called to mediate God's truth. The return of Christ, described as imminent and visible to all, is portrayed as both a day of judgment for the unrepentant and a glorious hope for the faithful, culminating in the assurance that God, who is eternally in control, will one day reveal Himself fully to His people.
