Romans 10:4 NIV

Galatians 3:24 niv
So the law was our guardian until Christ came that we might be justified by faith.

Romans 8:3-4 niv
For what the law was powerless to do because it was weakened by the flesh, God did by sending his own Son in the likeness of sinful flesh to be a sin offering. And so he condemned sin in the flesh, in order that the righteous requirement of the law might be fully met in us, who do not live according to the flesh but according to the Spirit.
