27 After this he went out, and saw a tax collector, named Levi, sitting at the tax office; and he said to him, "Follow me." 28 And he left everything, and rose and followed him. 29 And Levi made him a great feast in his house; and there was a large company of tax collectors and others sitting at table with them. 30 And the Pharisees and their scribes murmured against his disciples, saying, "Why do you eat and drink with tax collectors and sinners?" 31 And Jesus answered them, "Those who are well have no need of a physician, but those who are sick; 32 I have not come to call the righteous, but sinners to repentance."
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.
