1 Cor 1:27-31
27 Isn't it obvious that God deliberately chose men and women that the culture overlooks and exploits and abuses, 28 chose these "nobodies" to expose the hollow pretensions of the "somebodies"? 29 That makes it quite clear that none of you can get by with blowing your own horn before God. 30 Everything that we have — right thinking and right living, a clean slate and a fresh start — comes from God by way of Jesus Christ. 31 That's why we have the saying, "If you're going to blow a horn, blow a trumpet for God."
