The Number 666
Six is man’s number. Symbolically, 666 is man trying to be like God, but he falls short of perfection (the number seven). Only through Christ are we perfect, and symbolically we could be marked by His spiritual number of 777 (that is, if He were to have a number). Humanism epitomises the pride of man, as he tries to assume the role of God. (2 Thessalonians 2: 3-4) gives a perfect definition of humanism:
"Let no man deceive you by any means: for that day shall not come, except there come a falling away first, and that man of sin be revealed, the son of perdition; Who opposeth and exalteth himself above all that is called God, or that is worshipped; so that he as God sitteth in the temple of God, showing himself that he is God."
Those who allow Satan in their temple, declaring humanistic wisdom, are exalting themselves above God and opposing God. In the following list of common humanistic teachings, we can easily see the mark of the beast.
