17 What I mean is this: the Law, which came four hundred and thirty years later, does not invalidate a covenant previously ratified by God, so as to nullify the promise.
18 For if the inheritance is based on the law, it is no longer based on a promise; but God gave it to Abraham by a promise.
19 Why the Law then? It was added because of transgressions, having been ordained through angels by the agency of a mediator, until the seed would come to whom the promise had been made.
20 Now a mediator does not represent just one party; but God is one.
21 Is the law then opposed to the promises of God? Certainly not! For if a law had been given which could impart life, then righteousness would indeed have come by the law.
