A New Covenant

We are given a "New Covenant". But look WHO was given this NEW Covenant.

Jer 31:31 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:
Jer 31:32 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:
Jer 31:33 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.

This Covenant is given to the Hebrews.
HE goes on to say:

Jer 32:40 And I will make an everlasting covenant with them, that I will not turn away from them, to do them good; but I will put my fear in their hearts, that they shall not depart from me.

Paul tells us that those in Christ, are Jewish by faith.
Rom 2:28 For he is not a Jew, which is one outwardly; neither is that circumcision, which is outward in the flesh:
Rom 2:29 But he is a Jew, which is one inwardly; and circumcision is that of the heart, in the spirit, and not in the letter; whose praise is not of men, but of God.

So, for us to receive of this New Covenant, we also must accept the old Covenant. For the New Covenant says HE will put HIS laws in our hearts, and write them in our minds. This New Covenant never took the law away, but instead puts them in our hearts.

It is NOT the law that was nailed to the cross, it was the hand written traditions, all those extra do's and don't of the Pharisees.
Col 2:14 Blotting out the handwriting of ordinances that was against us, which was contrary to us, and took it out of the way, nailing it to his cross;
