John 11:42

42.And I knew that thou hearest me always. This is an anticipation, lest any one should think that he did not stand so high in favor with the Father, as to be able easily to perform as many miracles as he chose. He means, therefore, that there is so great an agreement between him and the Father, that the Father refuses him nothing; and even that he had no need to pray, because he only executed what he knew that the Father had enjoined; but in order that men may be more fully assured that this is truly a divine work, for this reason he called on the name of the Father. It will perhaps be objected, Why then did he not raise all the dead? The reply is easy. A certain fixed limit was assigned to miracles by the purpose of God, so far as he knew to be sufficient for confirming the Gospel.
