The stars, along with the sun and moon were created by God "to serve as signs to mark seasons and days and years" (Gen 1:14-18). The stars throughout history have been used for navigational purposes. When the starry sky is acknowledged, it is done to point to the Creator and although the heavens declare and show the handiwork of God, humanity is the pinnacle of His creation (Gen 1:26,27; Ps 8:3, 19:1).
God promised Abraham that his descendants would be as numerous as the stars in the sky, inferring too many for him to count or imagine, yet God has all the stars numbered and named (Gen 15:5; Ps 147:4). God arranged the stars into recognizable constellations (Job 9:9, 38:31,32). God uses the stars as a form of communication with humanity. An unusual star announced the birth of Jesus while the Bible states there will be unusual signs in the heavens at the end times (Isa 13:9,10; Joel 2:31, 3:15; Mt 2:2, 24:29,30; Lk 21:25-27).
Satan (Lucifer) is sometimes called the morning star (Isa 14:12).
Astrology, the ungodly assumption of the supposed influence of the stars and constellations on human affairs is not be confused with astronomy, which is the scientific study of the stars and their movements.
