27 After this he went out and saw a tax collector named Levi, sitting at the tax booth; and he said to him, "Follow me." 28 And he got up, left everything, and followed him. 29 Then Levi gave a great banquet for him in his house; and there was a large crowd of tax collectors and others sitting at the table with them. 30 The Pharisees and their scribes were complaining to his disciples, saying, "Why do you eat and drink with tax collectors and sinners?" 31 Jesus answered, "Those who are well have no need of a physician, but those who are sick; 32 I have come to call not 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.
