But if you 'love the LORD your God with all your heart, all your soul, and all your mind... and love your neighbor as yourself', you will choose to honour God and people by not murdering, stealing etc. It's about being obedient to Christ, out of love for Him and what He's done, not because the Law saves, it doesn't. The Law is all or nothing. You can't pick and choose which parts to follow. As Christians we no longer live under the burden of the Law.
If it is about being obedient to Christ and Christ is the great I AM who gave the Law...
Joh 8:58 Jesus said unto them, Verily, verily, I say unto you, Before Abraham was, I am.
And He revealed Himself to Moses...
Exo 3:14 And God said unto Moses, I AM THAT I AM: and he said, Thus shalt thou say unto the children of Israel, I AM hath sent me unto you.
And then I AM or the LORD (the word means Eternal, Ever-Living, Self Existent One) then said this...
Exo 20:1 And God spake all these words, saying,
Exo 20:2 I am the LORD thy God, which have brought thee out of the land of Egypt, out of the house of bondage.
Exo 20:3 Thou shalt have no other gods before me.
Speaking the Ten Commandments, not to Moses, but directly from Mt. Sinai to the people.
and then you tell me we are not under the Law but under Christ's Law?
As Li'l Abner used to say, "amoosin but confusin".
