Is numerology satanic?

Answer:

Numerology is "the study of the supposed occult influence of numbers on human affairs." Like astrology, numerology attempts to divine a person's character and future. In numerology, it is based on numbers related to a person, wherein astrology is based on positions of stars and planets. For example, the name and birth date of an individual would be used to analyze and define personality and possibilities.

You can tell that it is fake because there is no one system of interpreting numbers. Those given are stated in vague terms which can be interpreted in various ways. Since it is based on lies, it certainly not from God (John 8:44).
