Romans 5:16 — And not as it was by one that sinned, so is the gift: for the judgment was by one to condemnation, but the free gift is of many offences unto justification.
Our guilt is from one sin of one man — Adam.
The righteousness imputed to us by Christ is for all offenses.
The gift is contrasted with judgment — the gift for many is contrasted with condemnation because of one. Therefore, justification is greater than condemnation.
