Really?
What about the law of FAITH?
Are we not commanded by God to have faith?
Are we not commanded by God to love Him with all of our heart?
And are we not commanded to show that love by keeping God'a laws.....let's read it....
John 14
[15] If ye love me, keep my commandments.
[21] He that hath my commandments, and keepeth them, he it is that loveth me: and he that loveth me shall be loved of my Father, and I will love him, and will manifest myself to him.
So...just which laws are we no longer under?
.
Take John 14 into context with John 13:34-35 because Jesus Christ is talking about the Law of Christ.
Read carefully John 15:9-10
9 As the Father hath loved me, so have I loved you: continue ye in my love.
10 If ye keep my commandments, ye shall abide in MY love; even as I have kept MY FATHER'S COMMANDMENTS, and abide in his love.
(Notice how Jesus abode in His Father's love keeping the commandments in the letter to the "T" meaning every single law, which is something we cannot do because of our flesh (sinful nature) and the fact we have been sold into sin. Jesus had no sin or knew no sin but became sin for us redeeming us from the body of death regenerating our spirits thus becoming born again or born of God. We were created after God in righteousness true holiness in the spirit. (Ephesians 4:23) We obey from the heart Romans 6:17 and NOT after the letter Romans 7:6. Apart from faith, the letter produces dead works and ONLY partial obedience which is disobedience there are no gray spots you either obeyed fully or you failed to obey, hence why the letter kills because we can never obey fully to the "T". This is why the Law in the form of the letter is not of faith. Galatians 3:12. It seems that may law abiding sects advocating obedience according to the letter stumble over this simple truth. The Law in the form of the letter exposes what sin is and condemns sins BUT it does not serve as a restraint to sin since it's not of faith. The results are dead works, since the letter is not of faith. Those in the OT like Abraham, Jacob (Israel), David, Samuel etc. were all justified by faith and not by keeping the letter.
I've had this discussion with you sometime ago and you continue point to two distinct laws when that's not the case. The Law of God exists in the form of the letter (the 10 commandments written on stone) pertaining to our flesh in exposing sin and condemning it and the Law of Christ (Law of spirit and life) which requires the crucifying the flesh and following Jesus becoming his disciple. Cf. Luke 9:23 and Luke 14:26 with John 13:34-35
Now that we do not serve after the letter but in the spirit we see that the Law of God is fulfilled by the following two mentioned in the OP (John 6:28-29 and John 13:34-35) which reflects the 2 greatest commandment:
JOHN 6:28-29
28 Then said they unto him, What shall we do, that we might work the works of God?
29 Jesus answered and said unto them, This is the work of God, that ye believe on him whom he hath sent.
John 13:34-35
34 A new commandment I give unto you, That ye love one another; as I have loved you, that ye also love one another.
1 John 3:22-23
22 And whatsoever we ask, we receive of him, because we keep his commandments, and do those things that are pleasing in his sight.
23 And this is his commandment, That we should believe on the name of his Son Jesus Christ, and love one another, as he gave us commandment. (Notice how this reflects John 6:29 and John 13:34)
Now compare with these verses, if we truly love the Lord with all our hearts, souls and minds we will NOT or should NOT give him dead works produced by our flesh that is subject to the letter since we cannot obey it to the "T" and it is not of faith. However, God commands us to believe in His Son and abide in His love because Jesus abode in His Father's love perfectly obeying unto death. That covers the first great commandment the second great commandment is to love thy neighbour as thyself and that is fulfilled in the Law of Christ where Jesus states Love others AS I HAVE LOVED YOU which was to the death! This requires that we crucify our flesh daily to love after He loves which is spirit!
Matthew 22:35-40
35 By this shall all men know that ye are my disciples, if ye have love one to another.
36 Master, which is the great commandment in the law?
37 Jesus said unto him, Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind.
38 This is the first and great commandment.
39 And the second is like unto it, Thou shalt love thy neighbour as thyself.
40 On these two commandments hang all the law and the prophets.
Observe these verses from Hebrews 5:8-10 signifying how we are to Obey Christ which abode in His Father's love perfectly!
8 Though he were a Son, yet learned he obedience by the things which he suffered;
9 And being made perfect, he became the author of eternal salvation unto all them that obey HIM;
10 Called of God an high priest after the order of Melchisedec.
NOW Whosoever denieth the Son, the same hath not the Father: he that acknowledgeth the Son hath the Father also. 1 John 2:23
