I have never heard anyone born again by faith in Jesus say they pursue disobedience because of grace. I will say that letters, commandments, days, diets, traditions, feasts, are not the objective of the Christian life (Romans 6:14) but that obedience in the New Covenant is manifest through the anointing of the indwelling Holy Spirit (Ephesians 1:13-14; Galatians 5:16) who produces divine “fruit” through the redeemed and this fruit honors the father, fulfills all law and proves one to be a disciple of Jesus (Galatians 5:16-23; John 15:8). Keeping letters, concerning one’s self with Torah is not the objective of New Covenant relationship.
