If a stranger can see the glory, and if a stranger can give him praise, then what is wrong with you?
14And when he saw them, he said unto them, Go shew yourselves unto the priests. And it came to pass, that, as they went, they were cleansed.
15And one of them, when he saw that he was healed, turned back, and with a loud voice glorified God,
16And fell down on his face at his feet, giving him thanks: and he was a Samaritan.
17And Jesus answering said, Were there not ten cleansed? but where are the nine?
18 There are not found that returned to give glory to God, save this stranger.
19And he said unto him, Arise, go thy way: thy faith hath made thee whole.
One out of 10 will do what God has asked and receive the blessings of God. Although God will heal all 10, nine will remain unclean from within.
