The number 666 symbolizes man exalting himself as God. It is idolatrous humanism. It is what Adam reached for in the garden of Eden, and it is what lies of the heart of all idolatry. Truly, the hearts of humans are idol factories because sinful man desires to be like God. The number 666 perfectly matches the agenda of the beast and the false prophet to worship that which is created instead of the Creator. And chief of all things created is man.
In Revelation 13:16-18 we read the following about “the number of the beast”:
Also it causes all, both small and great, both rich and poor, both free and slave, to be marked on the right hand or the forehead, so that no one can buy or sell unless he has the mark, that is, the name of the beast or the number of its name. This calls for wisdom: let the one who has understanding calculate the number of the beast, for it is the number of a man, and his number is 666. (Rev. 13:16-18)
What is the meaning of “his number is 666” in this passage?
The Number Six Is Related to Man’s Creation on the Sixth Day, and It Has the Biblical Symbolic Value of Imperfection Due to Man’s Fall
The mark that the false prophet places on people is a sign of ownership and loyalty, indicating that the Antichrist beast is their lord and master. Their thoughts and actions are given to the service of the beast. The number six is related to man’s creation on the sixth day. It has the biblical symbolic value of imperfection due to man’s fall, while the number seven symbolizes divine perfection.
Six is repeated three times in Revelation 13:18 because repeating something three times represents the divine superlative (e.g., “‘Holy, holy, holy, is the Lord God Almighty, who was and is and is to come!’” (Rev. 4:8: see also Isa. 6:3).
