God himself made a vow. It is called in the Bible, a covenant. “This is the covenant I will make with the people of Israel after that time,” declares the LORD. “I will put my law in their minds and write it on their hearts. I will be their God, and they will be my people…I will forgive their iniquity, and I will remember their sin no more.” (Jeremiah 31:33-34). God kept his vow by sending Jesus to atone for our sins, and grant us the forgiveness we all need. For none of us has kept his vow perfectly. We can rejoice that God’s oath was kept and is for our eternal good.
