Amulek’s words began Zeezrom’s conversion, and Alma’s words and power in the Spirit intensify the conversion. What becomes interesting is that both the pre-repentant and post-repentant Zeezrom asked questions. The difference isn’t in asking questions, but in the intent behind the questions.
There was little desire for an answer to the first questions asked; they were designed for other purposes. Now, however, “Zeezrom began to inquire of them diligently.” Upon strongly feeling the Spirit, the questions continue, but the nature of the questions changes. Now they are sincere attempts to understand.
