Thy faith hath saved thee. The word save is restricted by some commentators to the cleanness of the flesh. [1] But if this be the case, since Christ commends the lively faith of this Samaritan, it may be asked, how were the other nine saved? for all of them without exception obtained the same cure. [2] We must therefore arrive at the conclusion, that Christ has here pronounced a different estimate of the gift of God from that which is usually pronounced by ungodly men; namely, that it was a token or pledge of God's fatherly love. The nine lepers were cured; but as they wickedly efface the remembrance of the grace of God, the cure itself is debased and contaminated by their ingratitude, so that they do not derive from it the advantage which they ought. It is faith alone that sanctifies the gifts of God to us, so that they become pure, and, united to the lawful use of them, contribute to our salvation. Lastly, by this word Christ has informed us in what manner we lawfully enjoy divine favors. Hence we infer, that he included the eternal salvation of the soul along with the temporal gift. The Samaritan was saved by his faith How? Certainly not because he was cured of leprosy, (for this was likewise obtained by the rest,) but because he was admitted into the number of the children of God, and received from His hand a pledge of fatherly kindness.

Go thy way - To the "priest;" for without "his" certificate he could not again be restored to the society of his friends, or to the public worship of God. Having now appropriately expressed your gratitude, go to the priest and obey the law of God. Renewed sinners, while their hearts overflow with gratitude to Jesus, "express" that gratitude by obeying God, and by engaging in the appropriate duties of their calling and of religion.

Thy faith hath made thee whole - Thy faith hath been the means of receiving that influence by which thou hast been cleansed.

And he said unto him, arise,.... For, as yet, he lay at his feet upon his face, adoring and praising him; nor did he attempt to rise till Jesus bid him: adding,
go thy way; to thine own country, town, or city, and to thy friends and relations, and about thy business:
thy faith hath made thee whole: or "saved thee", in soul, as well as body; that is, Christ, the object of faith, had saved him; for his salvation is ascribed to his faith, not as the efficient cause of it, but as that was wrought in him, and drawn forth from him, and exercised by him, in receiving this blessing from Christ, the author of it, even both corporeal and spiritual salvation.

Arise--for he had "fallen down on his face at His feet" (Luke 17:16) and there lain prostrate.
faith made thee whole--not as the others, merely in body, but in that higher spiritual sense with which His constant language has so familiarized us.
