Luke 17:15-19

And one of them, when he saw that he was healed Was so affected, that, with a heart full of gratitude and joy, he immediately turned back, and with a loud voice glorified God Made a free and open acknowledgment of the signal mercy which he had received. Though he had kept at a distance from Jesus before, yet being sensible that he was now perfectly clean, he came near, that all might have an opportunity of beholding the miracles; and fell down on his face at his feet In the deepest humiliation, giving him thanks as the immediate author of his cure; and yet this man was a Samaritan One of that heretical nation, from which one would have expected less of any thing good than from the Jews, the professors of the true religion, and members of God's visible church. Therefore, to make known the good disposition of the man, though he professed a false religion, and to intimate that the others, who had been more favoured with external privileges and advantages, ought to have showed as great a sense of piety and gratitude as he; Jesus said, Were there not ten cleansed, but where are the nine? Why did they not return to give thanks? This intimates that ingratitude is a very common sin; of the many that receive mercy from God, there are but few, very few, that return to give thanks in a right manner; that render according to the benefits done unto them. There are not found to give glory to God, save this stranger Ο αλλογενης ουτος, this alien Such, ever since the captivity, the Jews have considered the Samaritans. They call them Cuthites to this day. Thus many, who profess revealed religion, are outdone and quite shamed by some that are governed only by natural religion, and that not only in moral virtue, but in piety and devotion. “The ingratitude of these Jewish lepers, now cured, will appear monstrous, if we consider that the malady from which they were delivered is in itself one of the most loathsome diseases incident to human nature, and a disease which, by the law of Moses, subjected them to greater hardships than any distemper whatsoever. But though the cure of this dreadful affliction was produced without the smallest pain or even trouble to the lepers, and so speedily that it was completed by the time they had got a little way off, as appears by the Samaritan's finding Jesus where he left him, these Jews would not give themselves the trouble of returning to glorify God, by making the miracle public, nor to honour Jesus, by acknowledging the favour. Such were the people that gloried in their being holy, and insolently called the men of all other nations dogs. But their hypocrisy and presumption received a severe reprimand on this occasion. For our Lord, in his observations on their behaviour, plainly declared, that the outward profession of any religion, however true and excellent that religion may be in itself, is of no value before God in comparison of piety and inward holy dispositions.” Macknight.
