Matteo 9:13

But go ye and learn what that meaneth, I will have mercy and not sacrifice; for I am not come to call the righteous, but sinners, to repentance.

Jesus heard the murmuring and took the fault-finders to task. He quotes a proverb in explanation of His own conduct, implying, at the same time, a criticism of their position. A physician naturally finds his field of activity among the sick, such as feel the need of his services. Those that are well, or deceive themselves into the belief that they are in perfect health, resent the suggestion of a physician in their case.

Christ is the true Physician of the soul. He that is spiritually well, that is righteous and perfect, without sin, feels no need of the Savior of sinners. Though there are no just persons in the world that would honestly belong to this class, the great majority claim perfection, a complete righteousness, for themselves. They want nothing of Jesus, the Redeemer. Only the meek and lowly in heart, that feel their sin and the curse of sin, they come to the Friend of sinners and accept healing at His hands.

Jesus reminds the Pharisees, who might have felt the inference, of the word of the prophet, Hosea 6:6. Mercy goes before sacrifice. All service of the lips and sacrifices of the hands, all mere outward worship, all dead orthodoxy, is an abomination before the Lord. A merciful heart manifesting its sympathy in deeds of mercy pleases Him.

But the Pharisees of all times have never felt the need of the mercy of God, and therefore have never tasted its sublime sweetness. For that reason they feel no mercy towards their fellow-creatures. All those that are called after the name of Christ must be filled with the enthusiasm of the mission of Jesus.
