The Ten Commandments are part of the Law; GOD's Law; Christ the Word. HE and it through HIM has become part of who we are; being implanted in our hearts and minds. Christians can't help themselves. For GOD has said, I will put my Laws in their hearts and write them in their minds. Declared to be the epistle of Christ.... written not with ink, but with the Spirit of the living God; not in tables of stone, but in fleshy tables of the heart. And such trust have we through Christ to God-ward: Not that we are sufficient of ourselves to think any thing as of ourselves; but our sufficiency is of God. So Say not in thine heart, Who shall ascend into heaven? (that is, to bring Christ down from above

Or, Who shall descend into the deep? (that is, to bring up Christ (HIS Word; the Law) again from the dead.) But what saith it? The word (Christ; HIS LAW) is nigh thee, even in thy mouth, and in thy heart (that we do it): that is, the word of faith, which we preach. Christ in us the hope of glory. A new and living Way; the Veil; that is to say His flesh; the Body of Christ; the Temple of GOD. For it is HE that works in us both to will and do HIS good pleasure. Of his own will begat he us with the word of truth, that we should be a kind of firstfruits of his creatures. Wherefore lay apart all filthiness and superfluity of naughtiness, and receive with meekness the engrafted word, which is able to save your souls. But be ye doers of the (engrafted) word (that which is in our hearts and minds), and not hearers only, deceiving your own selves.
