2 Corinthians 3:4-6 - Paul's Competence
4 Now, confidence such as this we have, through the Christ, toward God; 5 not that we are able, of ourselves, to devise any thing, as from ourselves; but our ability is from God, 6 who has made us able ministers of the new covenant, not of letter, but. of spirit: for the letter kills, but the spirit makes alive.
