A saving intest in and a living union with Christ accomplishes both. Our Lord Jesus has forever freed us firm the curse of sin, being made a curse for us, and from the guilt of sin through His obediance and sacrifice. "There is therefore now no condemnation to them who are in Chnst Jesus" "Who shall lay anything to the charge of God's elect? It is God that justifieth" In Christ we have honored the law and satisfied God's justice; we are complete and perfect in Him!
Also, those believers who are "in Christ," by grace, by the power of the Spirit; and by faith, walk not after the flesh but after the Spirit; and they do mind the things of Christ. That is, they do love the conmmandments, doctrines, and all things pertaning to the kingdom of their Lord. They are concerned with His glory, and their thoughts are occupied with their relationship with Christ. Their affection is set on things above, not on the things of this world. It is a matter of being in love with and married to another (Rom. 7:1-6) "We are become dead to the law by the body of Christ that we should be married to Christ and bring forth fruit unto God" We are dead to the old husband who restrained us and held us captive. We are married to Christ and serve Him, not under obedience to written rules and regulations but in NEWNESS OF LIFE AND LOVE! The forced obedience of a man under law is the obedience of a slave. The obedience of a Son or a wife is the obedience of love (II Cor. 5:14).
