Matthew 9:11-12—“And when the Pharisees saw it, they said to His disciples, Why does your Teacher eat with the tax collectors and sinners? Now when He heard this, He said, Those who are strong have no need of a physician, but those who are ill.”
Note 1 on physician says: “In calling people to follow Him for the kingdom, the King of the heavenly kingdom ministered as a Physician, not as a Judge. A Judge’s judgment is according to righteousness, whereas a physician’s healing is according to mercy and grace.
Those whom He made people of His heavenly kingdom were lepers (8:2-4), paralytics (8:5-13; 9:2-8), the fever-ridden (8:14-15), the demon-possessed (8:16, 28-32), those ill with all kinds of diseases (8:16), despised tax collectors, and sinners (vv. 9-11). If He had visited these pitiful people as a Judge, all would have been condemned and rejected, and none would have been qualified, selected, and called to be the people of His heavenly kingdom. However, He came to minister as a Physician, to heal, recover, enliven, and save them that they might be reconstituted to be His new and heavenly citizens, with whom He could establish His heavenly kingdom on this corrupted earth.”
