"In their works"

1. Hel. 6: 38
   38 And it came to pass on the other hand, that the Nephites did build them up and support them, beginning at the more wicked part of them, until they had overspread all the land of the Nephites, and had seduced the more part of the righteous until they had come down to believe in their works and partake of their spoils, and to join with them in their secret murders and combinations.
2. 3 Ne. 27: 11
   11 But if it be not built upon my gospel, and is built upon the works of men, or upon the works of the devil, verily I say unto you they have joy in their works for a season, and by and by the end cometh, and they are hewn down and cast into the fire, from whence there is no return.
