Galatians 3:21-24 NIV

[21] Is the law, therefore, opposed to the promises of God? Absolutely not! For if a law had been given that could impart life, then righteousness would certainly have come by the law. [22] But Scripture has locked up everything under the control of sin, so that what was promised, being given through faith in Jesus Christ, might be given to those who believe. [23] Before the coming of this faith, we were held in custody under the law, locked up until the faith that was to come would be revealed. [24] So the law was our guardian until Christ came that we might be justified by faith.
