There were no ungrateful lepers among the Nephites. None of them missed the opportunity to express their gratitude with humble kisses and thankful tears. Although the Lord performed the same miracles among the Nephites as he had among the Jews, the response of those who were healed was not the same:
'And as he entered into a certain village, there met him ten men that were lepers, which stood afar off:
And they lifted up their voices, and said, Jesus, Master, have mercy on us.
And 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.
And one of them, when he saw that he was healed, turned back, and with a loud voice glorified God,
And fell down on his face at his feet, giving him thanks: and he was a Samaritan.
And Jesus answering said, Were there not ten cleansed? but where are the nine?
There are not found that returned to give glory to God, save this stranger.
And he said unto him, Arise, go thy way: thy faith hath made thee whole.' (Lu 17:12-19)
“All the Multitude with One Accord Did Go Forth with Their Sick and Their Afflicted and He Did Heal Them”
"This is neither a matter of satisfying curiosity nor a display of power for entertainment or wonder. This manifestation is…intimately connected with faith and salvation. The physical healing means nothing except as it is literally connected to the spiritual healing that the Savior has also brought about. This is certainly the sense in which the Savior instructs the leaders of his Nephite church regarding sinning and healing, as it applies to the unworthy member: 'Nevertheless, ye shall not cast him out of your synagogues or your places of worship, for unto such shall ye continue to minister; for ye know not but what they will return and repent, and come unto me with full purpose of heart, and I shall heal them; and ye shall be the means of bringing salvation unto them' (3 Nephi 18:32; emphasis added).
"All of this complex pattern of meaning comes together most dramatically in the physical act of stepping forward and kneeling before the Savior, the experience of literally coming unto Christ, of touching and being touched. That the physical and the spiritual are intertwined should come as no surprise to members of a church that places extraordinary emphasis on ordinances—those small occasions and gestures that allow all of us to participate in the great drama of salvation. To collapse the whole matter of our purpose in this life into one symbolic act would bring us an experience very close to that of the Nephites': 'And they did all, both they who had been healed and they who were whole, bow down at his feet, and did worship him; and as many as could come for the multitude did kiss his feet, insomuch that they did bathe his feet with their tears' (3 Nephi 17:10). Isn't this truly what it means to come unto Christ, to 'close with him' (as the Puritans used to say), to be invited to come forth, and, because of the preparations of both the Savior and the saved, to be accepted, literally and completely, doing—acting out what the words themselves describe?"
