Not that we are competent in ourselves to claim anything for ourselves, but our competence comes from God. He has made us competent as ministers of a new covenant—not of the letter but of the Spirit; for the letter kills, but the Spirit gives life. – 2 Corinthians 3:5-6
For what we preach is not ourselves, but Jesus Christ as Lord, and ourselves as your servants for Jesus’ sake. – 2 Corinthians 4:5
