The central message of this sermon is that God has a single, grand plan for the universe, which encompasses all of history and human experience. This plan includes Jesus' two comings: first as the savior who provides salvation, and second as the judge who will shatter earthly powers and establish the kingdom of God. The sermon highlights how this plan unfolds over time, with God's sovereignty and omniscience guiding every event, including those that may seem contrary to His will. This understanding advances a biblical theology of providence and predestination, affirming God's control and power in all things. Ultimately, the takeaway is that our lives are lived in an "in-between" time, between Jesus' first and second comings, and that we must understand and live with this reality, trusting in God's goodness and sovereignty despite the apparent chaos and evil in the world.
