He that
overcometh, the same shall be clothed in white raiment, and I will not blot out
his name out of the book of life, but I will confess his name before my Father,
and before his angels. (Rev 3:5)
This verse is a very strong text against the various theologies of
"eternal security," as it shows that the names of those contained in
the book of life (i.e., those who will be saved) is not static, but that one's
name can be "blotted out" (εξαλιφω [alt. "to erase"])
therefrom (i.e., the loss of one's justification). Contingent upon remaining in
the book of life (read: in a saved state), one must persevere to the end (cf.
Phil 2:12), or, as the Greek of this verse reads, one must be ο νικων
("the conquering one").
