“And he said unto them: Behold, I, Samuel, a Lamanite, do speak the words of the Lord which he doth put into my heart…And behold, an angel of the Lord hath declared it unto me, and he did bring glad tidings to my soul. And behold, I was sent unto you to declare it unto you also, that ye might have glad tidings; but behold ye would not receive me” (Helaman 13: 5, 7).
Despite his initially being cast out after he attempted to preach to the unrepentant Nephities in Zarahelma, Samuel was receptive to the voice of the Lord – which came to him with the directive that he should revisit the city. However, when he valiantly returned to continue delivering the message he had been called to relay, he was denied entry. Undeterred, he mounted the wall and resumed warning the people of the impending destruction to come, stemming from their wicked tendencies. He also prophesied of Christ’s arrival and that “whosoever shall believe on the Son of God, the same shall have everlasting life. And behold, thus hath the Lord commanded me, by his angel, that I should come and tell this thing unto you” (Helaman 14:8-9). Some Nephites were converted by his words, though many would not heed them and were incensed – yet Samuel was protected as “the Spirit of the Lord was with him, insomuch that they could not hit him with their stones either with their arrows” (Helaman 16:2).
