Our only power and success comes from God

 Are we beginning to be like those false teachers of yours who must tell you all about themselves and bring long letters of recommendation with them? I think you hardly need someone’s letter to tell you about us, do you? And we don’t need a recommendation from you, either! The only letter I need is you yourselves! By looking at the good change in your hearts, everyone can see that we have done a good work among you. They can see that you are a letter from Christ, written by us. It is not a letter written with pen and ink, but by the Spirit of the living God; not one carved on stone, but in human hearts.
We dare to say these good things about ourselves only because of our great trust in God through Christ, that he will help us to be true to what we say, and not because we think we can do anything of lasting value by ourselves. Our only power and success comes from God. He is the one who has helped us tell others about his new agreement to save them. We do not tell them that they must obey every law of God or die; but we tell them there is life for them from the Holy Spirit. The old way, trying to be saved by keeping the Ten Commandments, ends in death; in the new way, the Holy Spirit gives them life. 2 Corinthians 3:1-6
