Often used in composition with the same general import, but only with verbs (etc.) expressing motion (literally or figuratively).

1. into, unto, to, towards, for, among

"For" (as used in Acts 2:38 "for the forgiveness...") could have twomeanings. If you saw a poster saying "Jesse James wanted forrobbery", "for" could mean Jesse is wanted so he can commit arobbery, or is wanted because he has committed a robbery. The latersense is the correct one. So too in this passage, the word "for"signifies an action in the past. Otherwise, it would violate theentire tenor of the NT teaching on salvation by grace and not by works.
