What do the sun, moon, and stars represent in the Bible?

In Genesis 1:14-19, the sun, moon, and stars are created as lights in the firmament to divide day from night and serve as signs of seasons, days, and years. The sun represents Christ, the light of the world, who brings salvation and truth to humanity (John 8:12). The moon symbolizes the church and believers who reflect Christ's light, demonstrating His glory to the world (Philippians 2:15). The stars can be seen as a representation of God's elect, each uniquely known and named by Him, reflecting His promises and the magnitude of His salvation (Genesis 15:5, Psalm 147:4).
