If Jesus completely satisfied the requirements of the Law, then everyone who places faith in Jesus is free from any obligation to the Ten Commandments.
It should follow that those who place faith in Jesus Christ are obligated to obey Him and not the Ten Commandments. The law of Christ obligates us to greater things than the 10 Commandments. I am not suggesting that we should disobey the Ten Commandments. While we are obedient to Christ, we cannot be in violation of the Ten Commandments. I do not commit adultery, not because of the Law, but because I desire to honor Christ in my relationship with my wife, specifically in regard to my sexual behavior. The Law will not fill you with the Holy Spirit. The Law will not provide a crucifixion in which you can participate by faith to experience transformation of character through death to self. Jesus is greater than the Law.
We should not obey the Ten Commandments because we are in obedience to Christ.
2 Did you receive the Spirit by the works of the law, or by the hearing of faith?
10 For as many as are of the works of the law are under the curse;
13 Christ has redeemed us from the curse of the law…
25 Therefore the law was our tutor to bring us to Christ, that we might be justified by faith. 25 But after faith has come, we are no longer under a tutor.
4 But when the fullness of the time had come, God sent forth His Son, born of a woman, born under the law, 5 to redeem those who were under the law, that we might receive the adoption as sons.
4 You have become estranged from Christ, you who attempt to be justified by law; you have fallen from grace.
16 Walk in the Spirit, and you shall not fulfill the lust of the flesh. 18 …if you are led by the Spirit, you are not under the law.
22 But the fruit of the Spirit is love, joy, peace, longsuffering, kindness, goodness, faithfulness, 23 gentleness, self-control. Against such there is no law. 24 And those who are Christ’s have crucified the flesh with its passions and desires. 25 If we live in the Spirit, let us also walk in the Spirit.
