What does the Bible say about Christ as the ruling Savior?

In the sermon, Christ is presented as the ruling Savior who metaphorically divides light from darkness, much like how God assigned the sun and moon to govern day and night. Genesis 1:14-19 illustrates God's sovereignty over creation, and this sovereignty extends to Christ, who rules as the greater light in our spiritual lives. As the one who ultimately decides who will be saved and who remains in darkness, Christ's role as mediator is central in offering both guidance and redemption. His reign is described as not just passive but intensely active, ensuring that His purposes are fulfilled, particularly in relation to the salvation of God's elect.
