written on our hearts

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 & with the house of Judah.

It will not be like the covenant I made with their forefathers when I took them by the hand to lead them out of Egypt, because they did not remain faithful to my covenant, & I turned away 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 & they will be my people.  

No longer will a man teach his neighbor, or a man his brother, saying, "Know the Lord,"  because they will all know me, from the least of them to the greatest.    

For  I will forgive their wickedness and will remember their sins no more."

Hebrews 8:8-12, NIV
