19. Faith answered the objections which reason brought against God's command to Abraham to offer Isaac, by suggesting that what God had promised He both could and would perform, however impossible the performance might seem (Ro 4:20, 21).
      able to raise him--rather, in general, "able to raise from the dead." Compare Ro 4:17, "God who quickeneth the dead." The quickening of Sarah's dead womb suggested the thought of God's power to raise even the dead, though no instance of it had as yet occurred.

      in a figure--Greek, "in a parable." ALFORD explains, "Received him back, risen from that death which he had undergone in, under, the figure of the ram." I prefer with BISHOP PEARSON, ESTIUS, and GREGORY OF NYSSA, understanding the figure to be the representation which the whole scene gave to Abraham of Christ in His death (typified by Isaac's offering in intention, and the ram's actual substitution answering to Christ's vicarious death), and in His resurrection (typified by Abraham's receiving him back alive from the jaws of death, compare 2Co 1:9, 10); just as on the day of atonement the slain goat and the scapegoat together formed one joint rite representing Christ's death and resurrection. It was then that Abraham saw Christ's day (Joh 8:56): accounting God was able to raise even from the dead: from which state of the dead he received him back as a type of the resurrection in Christ.
