The Ten Commandments is God's Covenant for the Nations.
The Ten Commandments are given to an entire race, a bloodline, a nation.
The Ten Commandments are not a "personal" moral code, they are a covenantal code for a race over time (over the generations).
Nations/bloodlines to do get "born again," but entire races are called.
The tabernacle is for living stones.
Personal atonement is truly personal (Leviticus 1) with the sacrifice a animals without blemish by the man presenting the sacrifice.
