When Christians reject the keeping of the Ten Commandments (one or more of them) then they are indicating that they are both lukewarm toward CHRIST as their LORD and MASTER of their life and outside the Will of the FATHER…If they were not “nominal” Christians they would have the law written on their heart.
When CHRIST suggested that the people “eat HIS flesh” and “drink HIS blood” it meant much more then to foretell the future act of “taking communion.”, it was literally foretelling that the true bride of CHRIST would be so fully surrendered to CHRIST that the “LAW” would not be on stone tablets anymore but “consumed” by them and so then “written on the fleshy tables of their heart.”
The New Covenant would not be a cold one of stone tablets but of the “heart” and a marriage of sorts: being ONE with CHRIST…
John 6:54Authorized (King James) Version (AKJV): 54 Whoso eateth MY flesh, and drinketh MY blood, hath eternal life; and I will raise him up at the last day.
Psalm 40:8 AKJV: I delight to do THY Will my GOD: yea, THY Law is within my heart.
2 Corinthians 3:3Authorized (King James) Version (AKJV): 3 forasmuch as ye are manifestly declared to be the epistle of CHRIST ministered by us, written not with ink, but with the SPIRIT of the Living God; not in tables of stone, but in fleshy tables of the heart.
Jeremiah 31:33Authorized (King James) Version (AKJV): 33 but this shall be the covenant that I will make with the house of Israel; After those days, saith the LORD, I will put MY law in their inward parts, and write it in their hearts; and will be their GOD, and they shall be MY people.
