2 Corinthians 2:14-3:6
But thanks be to God, who in Christ always leads us in triumphal procession, and through us spreads in every place the fragrance that comes from knowing him. For we are the aroma of Christ to God among those who are being saved and among those who are perishing; to the one a fragrance from death to death, to the other a fragrance from life to life. Who is sufficient for these things? For we are not peddlers of God's word like so many; but in Christ we speak as persons of sincerity, as persons sent from God and standing in his presence.
Ministers of the New Covenant
Are we beginning to commend ourselves again? Surely we do not need, as some do, letters of recommendation to you or from you, do we? You yourselves are our letter, written on our hearts, to be known and read by all; and you show that you are a letter of Christ, prepared by us, written not with ink but with the Spirit of the living God, not on tablets of stone but on tablets of human hearts.
Such is the confidence that we have through Christ toward God. Not that we are competent of ourselves to claim anything as coming from us; our competence is from God, who has made us competent to be ministers of a new covenant, not of letter but of spirit; for the letter kills, but the Spirit gives life.
