Christianity forbids astrology and fortune-telling for several reasons:
1. **Divination Condemned**: Astrology is considered a form of divination, which is condemned in the Bible (Deuteronomy 18:10-14, Isaiah 47:13-14)[1][2].
2. **Idolatry**: It is seen as idolatry because it involves putting faith in celestial bodies rather than God[2][4].
3. **Determinism vs. Free Will**: Astrology's deterministic nature conflicts with Christian doctrines of free will and divine providence[3][4].
4. **Satanic Deception**: Some Christians believe astrology is a satanic deception that distracts from faith in God[1].
