Alma didn’t have the best people skills • Alma 32:14 And now, as I said unto you, that because ye were compelled to be humble ye were blessed, do ye not suppose that they are more blessed who truly humble themselves because of the word?
Alma didn’t have the best people skills • Alma 32:25 For I do not mean that ye all of you have been compelled to humble yourselves; for I verily believe that there are some among you who would humble themselves, let them be in whatsoever circumstances they might.
