Just gonna add a simple idea. Jesus said he fulfilled the law. If you follow Jesus' 2 commands all the ten laws are automatically falling under them. Love God, love others. Thats what the ten commandments were about. The sabbath rest was a forrunner to how our redeemed lives should be-- every day focusing on God, resting in Him, in constant communication with our Father in heaven. The old testament israelites did not have that fellowship with God. Every law, rule, feast and festival, were symbolic of our future relationship with the risen Savior, and our Father. Anything else is legalistic.
Keep My Commandments
Jesus Christ Is The Great (I Am) That Delivered The 10 Commandments To Moses.
John 14:12-21KJV
12 Verily, verily, I say unto you, He that believeth on me, the works that I do shall he do also; and greater works than these shall he do; because I go unto my Father.
13 And whatsoever ye shall ask in my name, that will I do, that the Father may be glorified in the Son.
14 If ye shall ask any thing in my name, I will do it.
15
If ye love me, keep my commandments.
16 And I will pray the Father, and he shall give you another Comforter, that he may abide with you for ever;
17 Even the Spirit of truth; whom the world cannot receive, because it seeth him not, neither knoweth him: but ye know him; for he dwelleth with you, and shall be in you.
18 I will not leave you comfortless: I will come to you.
19 Yet a little while, and the world seeth me no more; but ye see me: because I live, ye shall live also.
20 At that day ye shall know that I am in my Father, and ye in me, and I in you.
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.
Jesus Christ Upheld The 10 Commandments, Just One Example Below.
Matthew 15:4-9KJV
4 For God commanded, saying, Honour thy father and mother: and, He that curseth father or mother, let him die the death.
5 But ye say, Whosoever shall say to his father or his mother, It is a gift, by whatsoever thou mightest be profited by me;
6 And honour not his father or his mother, he shall be free. Thus have ye made the commandment of God of none effect by your tradition.
7 Ye hypocrites, well did Esaias prophesy of you, saying,
8 This people draweth nigh unto me with their mouth, and honoureth me with their lips; but their heart is far from me.
9 But in vain they do worship me, teaching for doctrines the commandments of men.
