Can horoscopes open doors to demonic activity?
Question 08061
The horoscope column in a newspaper or the astrology app on a phone may seem entirely harmless, and most people who glance at their daily horoscope would never describe themselves as involved in the occult. Yet Scripture treats astrology and the attempt to discern the future through the stars with the same seriousness it applies to every other form of divination, and the question of whether horoscopes can open doors to demonic activity deserves an honest biblical answer rather than a dismissive shrug.
Astrology in the Biblical World
Astrology was deeply embedded in the cultures surrounding ancient Israel. The Babylonians were among the most sophisticated practitioners, developing elaborate systems of celestial interpretation that influenced every aspect of their national life. It is no accident that Isaiah 47:13-14 addresses Babylon directly: “You are wearied with your many counsels; let them stand forth and save you, those who divide the heavens, who gaze at the stars, who at the new moons make known what shall come upon you. Behold, they are like stubble; the fire consumes them; they cannot deliver themselves from the power of the flame.” The prophet’s verdict is devastating. The astrologers of Babylon, for all their sophistication, cannot save themselves, let alone the nation they claim to guide.
God’s people were explicitly warned against this practice. Deuteronomy 4:19 cautions Israel: “And beware lest you raise your eyes to heaven, and when you see the sun and the moon and the stars, all the host of heaven, you be drawn away and bow down to them and serve them.” The heavenly bodies were created by God (Genesis 1:14-18) and declare His glory (Psalm 19:1), but they were never intended to be consulted for guidance about human affairs. The stars are part of God’s creation. They are not independent sources of spiritual knowledge.
Why Horoscopes Fall Under the Same Prohibition
A modern horoscope may seem far removed from Babylonian astrology, but the underlying principle is identical. The horoscope assumes that the position of celestial bodies at the time of a person’s birth determines or influences their personality, relationships, and future. This assumption is incompatible with the biblical teaching that God alone governs the future, that human beings have genuine moral freedom, and that guidance for life comes through His Word and His Spirit rather than through created objects in the sky.
The Hebrew word for “interpreting omens” (nachash) in Deuteronomy 18:10 covers exactly this kind of practice: reading signs in the natural world to predict or influence outcomes. Whether a person is reading animal entrails in the ancient Near East or consulting a star chart on a smartphone, the spiritual transaction is the same. It is the attempt to access hidden knowledge through means God has not authorised and has explicitly condemned.
Can This Really Open Doors to Demonic Activity?
The question must be answered honestly and without sensationalism. Not every person who reads a horoscope will experience overt demonic oppression. The danger is more subtle and more pervasive than that. Demonic strategy, as Scripture presents it, operates through deception (2 Corinthians 11:14), through the normalisation of practices that draw people away from God, and through incremental steps that seem insignificant individually but cumulatively create spiritual vulnerability.
When a person habitually consults horoscopes for guidance, something shifts in their spiritual orientation. They begin, even unconsciously, to look to created things rather than the Creator for direction. They begin to frame their expectations around what the stars supposedly predict rather than around what God has promised. This is precisely the kind of foothold that Ephesians 4:27 warns against: giving the devil a place, a topos, a piece of ground on which he can establish a presence in the person’s thinking and decision-making.
For some people, casual interest in astrology develops into deeper involvement with the occult. The person who begins with horoscopes may move to birth charts, then to consulting astrologers personally, then to other forms of divination. The trajectory is not inevitable, but it is well-documented in pastoral experience. Each step normalises the next, and the person’s capacity to discern the difference between God’s guidance and alternative spiritual sources erodes progressively.
The Christian Response
Believers are called to reject astrology in all its forms, including the casual glance at a horoscope. This is not legalism. It is faithfulness to a God who has promised to guide His people by better means. Proverbs 3:5-6 provides the alternative: “Trust in the LORD with all your heart, and do not lean on your own understanding. In all your ways acknowledge him, and he will make straight your paths.” The person who has God’s Word, God’s Spirit, and the fellowship of God’s people has everything needed for wise decision-making. Horoscopes offer nothing that God has not already provided, and they do so through channels He has forbidden.
So, now what?
If you have been in the habit of reading horoscopes, the step is simple: stop. Delete the app. Skip the column. Not because the horoscope itself has magical power, but because habitually looking anywhere other than God for guidance is a spiritual posture that needs correcting. If your involvement has gone deeper than casual reading, bring it honestly before God in confession and turn decisively away from it. The God who made the stars is infinitely more reliable than any chart that claims to read them, and His guidance is available to every believer who asks for it in faith (James 1:5).
