"That the righteousness of the law might be fulfilled in us, who walk not after the flesh, but after the Spirit." (Romans 8: 4)
We do not get rid of the law arbitrarily in our lives just because.
That would violate God's righteousness.
"This then is the message which we have heard of him, and declare unto you, that God is light, and in him is no darkness at all." (1 John 1: 5)
For this reason, Jesus spoke to the Israelites of His day:
"Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfill." (Matthew 5:17)
We can dispense with the law because Jesus Christ has fulfilled it, and fulfilled the payment for all our sin, i.e. breaking of the law.
"Whosoever committeth sin transgresseth also the law: for sin is the transgression of the law." (1 John 3:4)
"13And you, being dead in your sins and the uncircumcision of your flesh, hath he quickened together with him, having forgiven you all trespasses; 14Blotting out the handwriting of ordinances that was against us, which was contrary to us, and took it out of the way, nailing it to his cross; 15And having spoiled principalities and powers, he made a shew of them openly, triumphing over them in it." (Colossians 2: 13-15)
"Blotting out" is better rendered "made inoperative" or "nullified" in that because Jesus fulfilled the law and paid for our sins on the Cross, the Devil has no more right to charge mankind with sin against God or anyone else.
John assures his readers:
"1My little children, these things write I unto you, that ye sin not. And if any man sin, we have an advocate with the Father, Jesus Christ the righteous: 2And he is the propitiation for our sins: and not for ours only, but also for the sins of the whole world." (1 John 2: 1-2)
Jesus is now and forever our propitiation, and our High Priest:
"5So also Christ glorified not himself to be made an high priest; but he that said unto him, Thou art my Son, to day have I begotten thee. . .9And being made perfect, he became the author of eternal salvation unto all them that obey him; 10Called of God an high priest after the order of Melchisedec." (Hebrews 5, 9-10)
What is Jesus our High Priest doing today at the right hand of God the Father?
"33Who shall lay any thing to the charge of God's elect? It is God that justifieth. 34Who is he that condemneth? It is Christ that died, yea rather, that is risen again, who is even at the right hand of God, who also maketh intercession for us." (Romans 8: 33-34)
Jesus has fulfilled the righteousness of the law for us, so that we no longer are under law but under HIs grace to live sober and godly in Him today (Titus 2: 11-14)
