19Wherefore then serveth
the law? It was added because of transgressions, till the seed should come to whom the promise was made;
and it was ordained by angels in the hand of a mediator.  20Now a mediator is not a mediator of one, but God is one.
 21Is the law then against the promises of God?
God forbid: for if there had been a law given which could have given life, verily righteousness should
have been by the law.  22But the scripture
hath concluded all under sin, that the promise by faith of Jesus Christ might be given to them that
believe. (Galatians
3:19-22, King James
Version)
