FREEDOM FROM THE LAW IS NOT ANTINOMIAN
Wherefore the law was our schoolmaster to bring us unto Christ, that we might be justified by faith.Galatians 3:24-25
But after that faith is come, we are no longer under a schoolmaster.
But now we are delivered from the law, that being dead wherein we were held; that we should serve in newness of spirit, and not in the oldness of the letter.Romans 7:6
But that no man is justified by the law in the sight of God, it is evident: for, The just shall live by faith.Galatians 3:11-12
And the law is not of faith: but, The man that doeth them shall live in them.
When you believed the Gospel, your spirit was baptised into Christ [Galatians 3-26-27].
You also had your sinful flesh cut off, through your death and resurrection with Christ [Colossians 2:11-12]. This is spiritual circumcision.
Since you have the gift of righteousness by faith [Romans 5:17] and you’ve put off your sinful flesh [Colossians 2], then your righteousness is sealed [Romans 4:11, 5:1].
Therefore, you are permanently righteous before God [Romans 5:1], and do not need to keep the Law to please God [Romans 3:28, 8:7-8, 8:13-13].
When you died with Christ, you died to the Law [Romans 7:4].
Therefore, God has delivered you from the Law [Romans 7:6] and you are no longer under the Law [Galatians 3:24-25].
Consequently, you have been set free from the Law [Galatians 5:1], and the Law is now not of faith for you [Galatians 3:12].
Antinomian means “against the Law”.
Since God is not against the Law, and He has declared that you are not under the Law [Romans 6:14, 7:6, Galatians 3:24-25], it is not antinomian for you to refrain from putting yourself under the Law.
