For if there had been nothing wrong with the first covenant, no place would have been sought for another. But God found fault with the people and said: “The time is coming declares, the Lord, when I will make a new covenant with the house of Israel and with the house of Judah. It will not be like the covenant I made with their forefathers when I took them by hand to lead them out of Egypt, because they did not remain faithful to my covenant, and I turned a way from them,declares the Lord. This is the covenant I will make with the house of Israel after that time,declares the Lord. I will put my laws in their minds and write them on their hearts. I will be their God,and they will be my people….For I will forgive their wickedness and will remember their sins no more” (Hebrew 8:7-10, 12)

We are not under the old covenant as the children of Israel were after they came out of Egypt, for it has long since been proven that man could never keep his part. But Christ has become for us “the surety of a better covenant,” which is between himself and his father. It was a promise, on the one hand of eternal life, which God who can not lie promised to his son before the age began – a gift which was given to him for the church (Titus 1-2, 2 Timothy 1: 9), and on the other hand, the guarantee from the son that he would keep that which the father had given him.
