This provides a theological exposition centered on key concepts from the Book of Revelation, particularly addressing the mystery of God and the timing of Christ's second coming. It tackles the classic argument regarding God's goodness versus the existence of evil by asserting that Satan currently rules the world, and God's apparent delay in judgment is an act of patience and mercy to allow time for salvation. The text then focuses on the event of the seventh trumpet, which signifies the completion of God's mystery—the full revelation of Christ and the establishment of His eternal kingdom. Finally, it uses the biblical account of John consuming a scroll to illustrate the necessity for believers to fully appropriate and assimilate God's Word, which contains both the sweetness of salvation and the bitterness of impending judgment, urging them to actively share this truth with a world in need of hope.
