2 Corinthians 3:3-6

3:3 revealing that you are a letter of Christ, delivered by us, written not with ink but by the Spirit of the living God, not on stone tablets but on tablets of human hearts.

3:4 Now we have such confidence in God through Christ. 3:5 Not that we are adequate in ourselves to consider anything as if it were coming from ourselves, but our adequacy is from God, 3:6 who made us adequate to be servants of a new covenant not based on the letter but on the Spirit, for the letter kills, but the Spirit gives life.
