Matthew 17:18

And Jesus rebuked the devil, and he departed out of him; and the child was cured from that very hour.

A cry of the utmost weariness, almost of impatience. It includes all those present: the disciples, because of their lack of understanding and the smallness of their faith; all the people, because they were slow of heart to believe Him to be the Messiah. Faithless they are, having either too small a faith or no faith at all; and perverted, corrupt, turned the wrong way, unwilling to heed and to follow the way He was pointing out to them, the way of salvation and sanctification. They were permitting themselves to be led astray. He was weary of it all. He longed to be delivered of the dullness, the stupidity, the perverseness of this generation. But He was not unkind or ungracious. His words were a rebuke, not the peevish exclamation of a disappointed man. He had the boy brought to Him, He saw the evidence of the demon's power, He made use of His divine power in earnestly rebuking the demon, and the result was a complete cure from that very hour. The devil may sometimes, by God's permission, torture the body by some sickness, incurable before men, but the souls of them that put their trust in Jesus are in His hands, safe against all the Evil One's attempts to possess them.
