The conviction which these twelve men had of their defect in prayer arose from hearing their Lord and Master pray, but likewise from a sense of serious defect even when compared with John the Baptist’s training of his disciples in prayer. As they listened to their Lord pray (for unquestionably He must have been seen and heard by them as He prayed, who prayed with marvelous simplicity, and power, so human and so Divine) such praying had a stimulating charm for them. In the presence and hearing of His praying, very keenly they felt their ignorance and deficiency in prayer. Who has not felt the same ignorance and deficiency? We do not regret the schooling our Lord gave these twelve men, for in schooling them He schools us. The lesson is one already learned in the law of Christ. But so dull were they, that many a patient iteration and reiteration was required to instruct them in this Divine art of prayer. And likewise so dull are we and inapt that many a wearying patient repetition must be given us before we will learn any important lesson in the all-important school of prayer. This Divine Teacher of prayer lays Himself out to make it clear and strong that God answers prayer, assuredly, certainly, inevitably; that it is the duty of the child to ask, and to press, and that the Father is obliged to answer, and to give for the asking. In Christ’s teaching, prayer is no sterile, vain performance, not a mere rite, a form, but a request for an answer, a plea to gain, the seeking of a great good from God. It is a lesson of getting that for which we ask, of finding that for which we seek, and of entering the door at which we knock. A notable occasion we have as Jesus comes down from the Mount of Transfiguration. He finds His disciples defeated, humiliated and confused in the presence of their enemies. A father has brought his child possessed with a demon to have the demon cast out. They essayed to do it but failed. They had been commissioned by Jesus and sent to do that very work, but had signally failed. “And when he was come into the house, his disciples asked him privately, saying, Why could not we cast him out? And he said unto them, This kind can come forth by nothing but by prayer and fasting.” Their faith had not been cultured by prayer. They failed in prayer before they failed in ability to do their work. They failed in faith because they had failed in prayer. That one thing which was necessary to do God’s work was prayer. The work which God sends us to do cannot be done without prayer. In Christ’s teaching on prayer we have another pertinent statement. It was in connection with the cursing of the barren fig tree: “Jesus answered and said unto them, Verily I say unto you, if ye have faith, and doubt not, ye shall not only do this which is done to the fig tree, but also if ye shall say unto this mountain, Be thou removed and be thou cast into the sea; it shall be done.
