The Virtue of Gratitude
1. Go to Jesus for mercy (11-14)
The command to go to the priests is a test of faith and obedience. It also implies that the completion of the cure took place at a distance without Jesus having touched the men
He did not come to them or touch them. He did not even say, ‘You are cured!’ He told them, leprous as they were, to go and show themselves to the priests, the normal procedure when a leper was cured. The priest acted as a kind of health inspector to certify that the cure had in fact taken place (Lev. 14:2ff.). Jesus was putting their faith to the test by asking these men to act as though they had been cured. And as they obeyed so it happened
2. Go to Jesus with gratitude (15-16)
His praising of God shows that he saw the hand of God in the cure and that he was ready to let everybody know about it.
If people do not give thanks quickly, they usually do not do so at all.
3. Go to Jesus for salvation (17-19)
The non-Jew with no religious privileges has shown a better understanding of the situation than the Jews.
All were cleansed and had an equal motive for gratitude. It might have been expected that all would give praise to God. But apparently the nine were so absorbed in their new happiness that they could not spare a thought for its source.
You recall that he loved the one who was thankful, but he was angry with the ungrateful ones, because they did not acknowledge their Deliverer. They thought more highly of their cure from leprosy than of him who had healed them.…
The story does not necessarily imply that the other nine lacked faith; the point is rather that their faith was incomplete because it did not issue in gratitude.
Full restoration means a saved soul as well as a sound body.
