Your missing something really important. Christians have a law, its given of the risen Christ. Doing the best we think we can to keep mosses law is not what Christ is looking for from us. We must be found in Christ Jesus believing and walking in obedience to him. Hear ye him. That law will not condemn all that are found in Christ Jesus. We can, with eyes to see and ears to hear see and hear what Christ is looking for from his people. His law will be written on the hearts of all who have his Spirit.He didn’t fulfill the law in terms of abolishing it:
Matthew 5:17
7 Do not think that I have come to destroy the law or the prophets. No, I have not come to destroy them, but to fulfil them. 18 For truly I say to you, till heaven and earth perish, not one jot or one tittle of the law shall escape, till all be fulfilled. 19 Whosoever breaks one of the least of these commandments, and teaches men so, he will be called the least in the kingdom of heaven. But whosoever observes and teaches them, the same will be called great in the kingdom of heaven.
“Has all been fulfilled?”
If no - then not one little thing in the law is done away with.
How do you fulfill the first and greatest commandment? Love the Most High with all your heart, soul, and strength?
How did the faithful and good servants of old show their love? How about for starters - not doing the things he says he despises. If he despises something - avoid it. That’s one way you can show love. That’s where the law/instructions/commandments come into play. In Paul’s time - people knew the law of Moses much better than today. Because it was preached in every city. Today - the law of Moses is rarely preached and behold - lawlessness has followed. Coincidence? I don’t think so. So I most definitely won’t stand on any side that teaches the law was done away with, and have to potentially drink the cup of wrath that goes with it.
John 15:9-12
King James Version
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.
11 These things have I spoken unto you, that my joy might remain in you, and that your joy might be full.
12 This is my commandment, That ye love one another, as I have loved you.
