"Under the Old Covenant, everything was a constant reminder of sin. In this New Covenant, God makes four promises. Those promises are "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, they will all know me, from the least of them to the greatest, I will forgive their wickedness and will remember their sins no more (Hebrews 8:10-12). God, in his glory and grace, guaranteed these four promises by the finished work of Christ and delivered them to you by His resurrected life.
