15 To give a human example, brothers: even with a man-made covenant, no one annuls it or adds to it once it has been ratified. 16Now the promises were made to Abraham and to his offspring. It does not say, “And to offsprings,” referring to many, but referring to one, “And to your offspring,” who is Christ. 17This is what I mean: the law, which came 430 years afterward, does not annul a covenant previously ratified by God, so as to make the promise void. 18For if the inheritance comes by the law, it no longer comes by promise; but God gave it to Abraham by a promise. 19Why then the law? It was added because of transgressions, until the offspring should come to whom the promise had been made, and it was put in place through angels by an intermediary. 20Now an intermediary implies more than one, but God is one. 21Is the law then contrary to the promises of God? Certainly not! For if a law had been given that could give life, then righteousness would indeed be by the law. 22But the Scripture imprisoned everything under sin, so that the promise by faith in Jesus Christ might be given to those who believe. 23Now before faith came, we were held captive under the law, imprisoned until the coming faith would be revealed. 24So then, the law was our guardian until Christ came, in order that we might be justified by faith. 25But now that faith has come, we are no longer under a guardian, 26for in Christ Jesus you are all sons of God, through faith.
7What then shall we say? That the law is sin? By no means! Yet if it had not been for the law, I would not have known sin. For I would not have known what it is to covet if the law had not said, “You shall not covet.”
24Wretched man that I am! Who will deliver me from this body of death? 25Thanks be to God through Jesus Christ our Lord! So then, I myself serve the law of God with my mind, but with my flesh I serve the law of sin.
