From death unto death (ek qanatou ei qanaton). From one evil condition to another. Some people are actually hardened by preaching. And who is sufficient for these things? (kai pro tauta ti ikano?). Rhetorical question. In himself no one is. But some one has to preach Christ and Paul proceeds to show that he is sufficient. For we are not as the many (ou gar esmen w oi polloi). A bold thing to say, but necessary and only from God ( Ephesians 3:6 ).
