Beale writes, "[r]egardless of whatever precise historical identifications could be given of the unbeliever's mark, the primary focus is on spiritual identification with the satanic beast" (261). Beale insists that the number 666 is not "some literal number of someone's name" (261) due to the fact that the saints have Christ's and God's name written on their foreheads. The saints' forehead identification is, according to Beale, clearly a spiritual reality and therefore the beastly mark must be as well.
Beale clarifies, " the triple six is intended as a contrast with the divine sevens throughout the book and signifies incompleteness and imperfection" (261). Those who are marked with the number of the beast are those who have identified themselves with the beast; they have aligned their thoughts and desires with the sinful, beast-like, epitome of incompleteness and imperfection.
Thus the number in revelation 13:18 is that of incomplete humanity apart from Christ. The beast is the supreme representative of unregenerate humanity, separated from God and unable to achieve divine likeness but always trying ... The triple sixes emphasize that the beast and his followers fall short of God's creative purposes for humanity." (261)
