Therefore being justified by faith, we have peace with God through our Lord Jesus Christ:

Faith gives us peace with God, not the law. For it reconciles us to God by taking away those sins which had made us God’s enemies. And because the Lord Jesus is the minister of this grace, it is through him that we have peace with God. Faith is greater than the law because the law is our work, whereas faith belongs to God. Furthermore, the law is concerned with our present life, whereas faith is concerned with eternal life. But whoever does not think this way about Christ, as he ought to, will not be able to obtain the rewards of faith, because he does not hold the truth of faith. Commentary on Paul’s Epistles.
