Since the disciples did not understand that He had called death sleep, He revealed it more clearly, saying, "He has died." He says that He rejoices, not from love of glory because He intends to perform a miracle, but because this would become an occasion for the disciples' faith. The saying, "that I was not there," has this meaning: if I had been there, he would not have died, for I would have had mercy on him even in a slight illness. But now death has occurred in My absence, so that by raising him I may give you great benefit for your faith in Me. Christ says this not because He performs divine works only when He is present. Rather, He says that, had He been present, He would not have allowed His friend to come under death's dominion. And He says, "Let us go to him," as to one who is alive. For the dead live for Him as God, since they are to live.
