What is the New Covenant?
"Here, the days are coming," says ADONAI, "when I will make a new covenant with the house of Isra'el and with the house of Y'hudah. It will not be like the covenant I made with their fathers on the day I took them by their hand and brought them out of the land of Egypt; because they, for their part, violated my covenant, even though I, for my part, was a husband to them," says ADONAI. "For this is the covenant I will make with the house of Isra'el after those days," says ADONAI: "I will put my Torah within them and write it on their hearts; I will be their God, and they will be my people. Jeremiah 31:31-33 CJB
For I will take you from among the nations, gather you from all the countries, and return you to your own soil. Then I will sprinkle clean water on you, and you will be clean; I will cleanse you from all your uncleanness and from all your idols. I will give you a new heart and put a new spirit inside you; I will take the stony heart out of your flesh and give you a heart of flesh. I will put my Spirit inside you and cause you to live by my laws, respect my rulings and obey them. Ezekiel 36:24-37
