According to Saint John Chrysostom, the Apostle spoke as though saying: "Is it not madness to strive in every way for this hope to be fulfilled, and then persecute the one who believes in it?" He offers two proofs of the resurrection: one from the prophets, and the other, stronger proof, from deeds. If the Jews had held no such belief, and had not been brought up in it, but it were only now being introduced, one might reject this teaching. The Apostle has in view specifically the resurrection of Jesus Christ, verse 9. Yet he makes the concept of resurrection general. He uses the word neither in the past tense, concerning the Lord's resurrection, nor in the future, concerning the general resurrection of the dead. He uses the present tense, showing that God is always able to raise the dead. He asks whether they truly do not believe this, and whether they consider such a deed incredible for almighty God.
