Verses 1-11 When Christ had done preaching, he told Peter to apply to the business of his calling. Time spent on week days in public exercises of religion, need be but little hinderance in time, and may be great furtherance to us in temper of mind, as to our worldly business. With what cheerfulness may we go about the duties of our calling, when we have been with God, and thus have our worldly employments sanctified to us by the word and prayer! Though they had taken nothing, yet Christ told them to let down their nets again. We must not abruptly quit our callings because we have not the success in them we desire. We are likely to speed well, when we follow the guidance of Christ's word. The draught of fishes was by a miracle. We must all, like Peter, own ourselves to be sinful men, therefore Jesus Christ might justly depart from us. But we must beseech him that he would not depart; for woe unto us if the Saviour depart from sinners! Rather let us entreat him to come and dwell in our hearts by faith, that he may transform and cleanse them. These fishermen forsook all, and followed Jesus, when their calling prospered. When riches increase, and we are tempted to set our hearts upon them, then to quit them for Christ is thankworthy.
Verses 12-16 This man is said to be full of leprosy; he had that distemper in a high degree, which represents our natural pollution by sin; we are full of that leprosy; from the crown of the head to the sole of the foot there is no soundness in us. Strong confidence and deep humility are united in the words of this leper. And if any sinner, from a deep sense of vileness, says, I know the Lord can cleanse, but will he look upon such a one as me? will he apply his own precious blood for my cleansing and healing? Yes, he will. Speak not as doubting, but as humbly referring the matter to Christ. And being saved from the guilt and power of our sins, let us spread abroad Christ's fame, and bring others to hear him and to be healed.
Verses 17-26 How many are there in our assemblies, where the gospel is preached, who do not sit under the word, but sit by! It is to them as a tale that is told them, not as a message that is sent to them. Observe the duties taught and recommended to us by the history of the paralytic. In applying to Christ, we must be very pressing and urgent; that is an evidence of faith, and is very pleasing to Christ, and prevailing with him. Give us, Lord, the same kind of faith with respect to thy ability and willingness to heal our souls. Give us to desire the pardon of sin more than any earthly blessing, or life itself. Enable us to believe thy power to forgive sins; then will our souls cheerfully arise and go where thou pleasest.
Verses 27-39 It was a wonder of Christ's grace, that he would call a publican to be his disciple and follower. It was a wonder of his grace, that the call was made so effectual. It was a wonder of his grace, that he came to call sinners to repentance, and to assure them of pardon. It was a wonder of his grace, that he so patiently bore the contradiction of sinners against himself and his disciples. It was a wonder of his grace, that he fixed the services of his disciples according to their strength and standing. The Lord trains up his people gradually for the trials allotted them; we should copy his example in dealing with the weak in faith, or the tempted believer.
