New Defender's Study Bible Notes
26:8 a thing incredible. It would be incredible if anyone but God (or those empowered by him) should claim to raise the dead, for only He is the Creator of life. To Paul, it was both anomalous and sad that the Jews, especially the Pharisees, whose hope was centered in the coming Messiah and the promised resurrection, should now be denying that Jesus had proved He was the Messiah by the very fact of His fulfillment of their hope. They believed in the doctrine of the resurrection, especially when the evidence was so strong that many Pharisees (including Paul) already had believed.
