As I'm reading these verses about Ammon's faithfulness as a servant to King Lamoni, the words of the Savior come to mind: "Whosoever will be great among you, let him be your minister; And whosoever will be chief among you, let him be your servant:" (Matthew 20:26-27) So back in Alma in verse 13, we read "And one of the king’s servants said unto him [Ammon], Rabbanah, which is, being interpreted, powerful or great king, considering their kings to be powerful; and thus he said unto him: Rabbanah, the king desireth thee to stay." Suddenly, because of his faithfulness as a servant to the king, the other servants were now calling him a great and powerful king.
On the topic of praise, I should note a few other references. I think praise often gets in the way of the Lord's work, becoming an end and a road block to further opportunities to teach. Christ himself deflected praise when he said, "Why callest thou me good? none is good, save one, that is, God."
Pres. Uchtdorf once taught, referencing Pres. James E. Faust,
He explained also how gracious the members of the Church are, especially to General Authorities. He said, “They will treat you very kindly. They will say nice things about you.” He laughed a little and then said, “Dieter, be thankful for this. But don’t you ever inhale it.”Pres. Uchtdorf goes on to teach:
We know that the contribution we can make by ourselves is small; nevertheless, as we exercise the power of the priesthood in righteousness, God can cause a great and marvelous work to come forth through our efforts. We must learn, as Moses did, that “man is nothing,"(Moses 1:10) by himself but that “with God all things are possible."(Matthew 19:26)
