Galatians 3:24 Wherefore the law was our schoolmaster to bring us unto Christ, that we might be justified by faith. 25 But after that faith is come, we are no longer under a schoolmaster.
God used the law to teach us of our need of Christ. We needed to understand how bad off we were or we wouldn’t have turned from our sin and self to Him. The law’s purpose was to get me to Christ.
Notice that after we get to Christ we are no longer under the law, our old schoolmaster. I think that is hard for most of us to accept, believe, even deal with. We are under grace.
We are new creatures. We have new desires. We will live out the law but it will not hang heavily over our heads. Our sins are forgiven. Our past is exchanged with that of Christ. We have salvation that was given to us and never earned.
We are not in school any more. We are now under grace!
