2 Corinthians 3:2-5
3:2 You yourselves are our letter,
written on our hearts, known and read by everyone,
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,
