to or into (indicating the point reached or entered) of place time or (figuratively) purpose (result etc.); also in adverbial phrases.

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