Jamieson, Fausset and Brown on 1 Corinthians 15:35

35. How--It is folly to deny a fact of REVELATION, because we do not know the "how." Some measure God's power by their petty intelligence, and won't admit, even on His assurance, anything which they cannot explain. Ezekiel's answer of faith to the question is the truly wise one (Eze 37:3). So Jesus argues not on principles of philosophy, but wholly from "the power of God," as declared by the Word of God (Mt 19:26; Mr 10:27; 12:23; Lu 18:27).

come--The dead are said to depart, or to be deceased: those rising again to come. The objector could not understand how the dead are to rise, and with what kind of a body they are to come. Is it to be the same body? If so, how is this, since the resurrection bodies will not eat or drink, or beget children, as the natural bodies do? Besides, the latter have mouldered into dust. How then can they rise again? If it be a different body, how can the personal identity be preserved? Paul answers, In one sense it will be the same body, in another, a distinct body. It will be a body, but a spiritual, not a natural, body.
