I do not set aside God’s grace, because if righteousness could come through the law, then Christ died for nothing!

Why then was the law given? It was added because of transgressions, until the arrival of the descendant to whom the promise had been made. It was administered through angels by an intermediary.

and when James, Cephas, and John, who had a reputation as pillars, recognized the grace that had been given to me, they gave to Barnabas and me the right hand of fellowship, agreeing that we would go to the Gentiles and they to the circumcised.
