Now you are changing direction. I have already proven that the Law of Moses (under the Old Covenant) was regarded as the LAW OF GOD. It follows that not obeying the [universal] moral law is sin. However, ALL the practices and traditions of the Old Covenant are no longer required under the NEW. Jesus revealed this when He said "You have heard it said (by teachers of the Old Covenant) BUT I SAY.
What He commanded included the moral essence of the OLD while elevating it to an entirely new level.
You have not proved the law of God, the Ten Commandment's is the law of Moses- I asked for you to find the name of Moses in His laws, you have yet to do so.
Exo 20:6 but showing mercy to thousands, to those who love Me and keep My commandments.
Who is the "Me" and "My"
Jesus did exactly what He promised to do with the law...the Law of Moses was temporary until the Seed Gal3:19 Heb10:1-15 Col2:14-17
Heb 9:27 Then he shall confirm a [k]covenant with many for one week;
But in the middle of the week
He shall bring an end to sacrifice and offering.
The law of God, the Ten Commandments He magnified- which means makes greater - connecting our inwards thoughts to the outward actions, anger with thou shalt not murder lust with those shalt not commit adultery- teaching us from this same unit not to break or teach others to break the least of these commandments-Mat5:19-30
Isa 42:21 The Lord is well pleased for his righteousness' sake; he will magnify the law, and make it honourable.
The law of Moses was never under the mercy seat of God, it was besides the ark as a witness against thee, the law that defines sin is the law of God that God wrote under His mercy seat where His blood atones for our sins. Removing the law of God and claiming its not His moral law or standard of righteousness Psa 119:172 Isa 56:1-2 which is everlasting Psa 119:142 doesn;t remove the law, it just removes what God covers with His mercy Exo20:6 Pro28:13 and not a good place to be come judgement day. Why God's people keep the commandments of God- His version through love and faith Rev14:12 Its best to allow God be God and allow Him to define what things are. God wrote God spoke His moral law, not Moses, its in God's Temple Rev15:5 Rev11:19, not Moses.
