27 And after these things he went forth, and beheld a tax-gatherer, by name Levi, sitting at the tax-office, and said to him, 'Be following me;' 28 and he, having left all, having arisen, did follow him. 29 And Levi made a great entertainment to him in his house, and there was a great multitude of tax-gatherers and others who were with them reclining (at meat), 30 and the scribes and the Pharisees among them were murmuring at his disciples, saying, 'Wherefore with tax-gatherers and sinners do ye eat and drink?' 31 And Jesus answering said unto them, 'They who are well have no need of a physician, but they that are ill: 32 I came not to call righteous men, but sinners, to reformation.'
Matthew Henry's Commentary on Luke 5:27-32
Commentary on Luke 5:27-39
(Read Luke 5:27-39)
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.
