We are new creation in Christ Jesus. No longer of the letter. An observance to that which was written on tables of stone and on parchment. For GOD has said
I will circumcise your heart, and the heart of your seed (with the circumcision of Christ), to love Jehovah your God with all your heart, and with all your soul, that you may live. For you shall listen to the voice of Jehovah your God, to keep His commandments and His statutes which are written in the book of this law. For you shall turn back toward Jehovah your God, with all your heart and with all your soul. For this command which (HIS commandments and statutes written in the book of the Law; the Word; Christ) I am commanding you day is not too wonderful for you, nor is it too far off. It is not in the heavens that you should say, Who shall go up into the heavens for us, and bring it to us, and cause us to hear it, that we may do it? And it is not beyond the sea that you should say, Who shall cross over for us to the region beyond the sea and take it for us, and cause us to hear it, that we may do it? For the word (His Commandments and statutes written in the book of the Law; the Word; Christ) is very near to you, in your mouth and in your heart, that you may do it. That is the word of faith in which we preach. And this word of faith; Christ in you the hope of glory is the end of the law; that which is written parchment and tables of stone for righteousness for all that believe. A new ministration! Not on tables of stone but on the fleshly tables of the heart. This is and was GOD's intention from the beginning. But due to our stiff necks and hard hearts it wasn't realized and fulfilled in most. So HE reprophesied it in Jeremiah.
Behold, the days come, saith the LORD, that I will make a new covenant with the house of Israel, and with the house of Judah: Not according to the covenant that I made with their fathers in the day that I took them by the hand to bring them out of the land of Egypt; which my covenant they brake, although I was an husband unto them, saith the LORD: 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 (My commandments and statutes written in the book of the law; the word; Christ) in their inward parts, and write it in their hearts; (that they may do it) and I will be their God, and they shall be my people. This is the faith in which we preach. And this faith has been available through Christ since the beginning.
