Astrology and the Bible: Why Christians Must Avoid It
Do you base your decisions on horoscopes or zodiac signs? Many today rely on astrology to guide their lives, unaware of its spiritual implications. But what does the Bible say about astrology? Is it simply a harmless belief—or is it something much more spiritually dangerous?
What Is Astrology?
Astrology is a form of divination—the occult practice of seeking knowledge of the future through supernatural means. It teaches that the positions of the sun, moon, planets, and stars influence human lives and world events. This pseudoscience has been practiced since ancient Babylon, where priests interpreted celestial patterns in connection with their gods.
The Babylonians developed the zodiac—twelve constellations that the sun appears to move through over the course of a year. Over time, people began associating personality traits, destinies, and guidance with these star signs. Today, astrology continues to thrive in horoscopes, psychic readings, and even apps that deliver “daily guidance.”
But is this compatible with God’s truth? Absolutely not.
Bible Verses That Warn Against Astrology
God's Word is clear: astrology is a sin. It leads people away from trust in Him and opens the door to demonic influence. Here are key Scriptures:
-
Deuteronomy 4:19 (NIV):
“When you look up to the sky and see the sun, moon, and stars... do not be enticed into bowing down to them or worshiping them.” -
Deuteronomy 17:3 (NIV):
"...who has worshiped other gods, bowing down to them or to the sun or the moon or the stars..." -
Isaiah 47:13-14 (NIV):
“Let your astrologers come forward... Surely they are like stubble; the fire will burn them up.” -
Jeremiah 10:2 (NIV):
“Do not learn the ways of the nations or be terrified by signs in the sky.” -
Daniel 1:20 (NIV):
Daniel and his companions were ten times wiser than all the magicians and enchanters of Babylon. Why? Because they followed God—not the stars.
God does not want His people to seek spiritual direction from the sky but from His voice and His Word.
The Purpose of the Heavens
God did create the heavens with purpose, but not for mystical guidance. Instead, the stars declare His glory:
-
Psalm 19:1-2 (NIV):
“The heavens declare the glory of God; the skies proclaim the work of His hands.” -
Genesis 1:14 (NIV):
“Let them serve as signs to mark seasons and days and years…” -
Isaiah 40:26 (NIV):
“Lift your eyes and look to the heavens… He who brings out the starry host one by one calls them each by name.”
Stars point to the Creator, not to our destinies. When people use the stars for divination, they replace God with false spiritual forces. That is idolatry.
Astrology Is Idolatry and Occult
Astrology is not harmless entertainment. It is a deceptive form of idolatry, worshiping the creation rather than the Creator. It invites spirits that do not come from God and subtly opens people to other occult practices—like tarot, crystals, or mediumship.
Even the Muslim crescent moon symbol can be traced to pre-Islamic moon worship. Islam’s founder, Muhammad, came from a culture steeped in astrology and paganism. This connection should alarm believers who dabble in “Christian astrology” or try to reconcile star signs with Scripture.
Real Stories, Real Consequences
Astrology has deceived many. Some have made major life decisions—like investments or marriage—based on planetary alignments. Others have suffered emotionally and spiritually by believing daily horoscopes or personality charts.
King Saul fell into this trap when he sought a medium at Endor. God punished him with death for consulting the dead instead of seeking the Lord (1 Samuel 28). In the same way, Christians today can suffer spiritual oppression when they open doors to occult influences—even unknowingly.
Use Biblical Discernment
To determine if a belief or practice lines up with Scripture, ask yourself:
-
Who founded this practice?
-
What were their spiritual beliefs?
-
What culture did it come from?
-
Did it honor God or false gods?
-
What does the Bible say about it?
Astrology fails every one of these tests. It originated in pagan cultures, honors celestial bodies, and encourages people to trust in created things rather than the Creator.
Final Warning: Trust in the Lord, Not the Stars
Proverbs 3:5-6 tells us to trust in the Lord with all our heart and lean not on our own understanding. That includes not trusting horoscopes, zodiac signs, or planetary alignments.
God alone knows the future. He is the source of wisdom, not the stars. If you've engaged with astrology, repent, renounce it in Jesus' name, and ask the Holy Spirit to guide your life.
