27 After these things He went out and saw a tax collector named Levi, sitting at the tax office. And He said to him, "Follow Me." 28 So he left all, rose up, and followed Him. 29 Then Levi gave Him a great feast in his own house. And there were a great number of tax collectors and others who sat down with them. 30 And their scribes and the Pharisees complained against His disciples, saying, "Why do You eat and drink with tax collectors and sinners?" 31 Jesus answered and said to 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.
