Alma 19
I wonder what Ammon was doing for those two days? Perhaps he was praying for Lamoni and/or direction from the Lord. Did he, at any time believe that Lamoni had died? Ammon did understand what it was like to have so much darkness of mind that having the gospel of Christ truly revealed to it would be overpowering – it had happened to his friend Alma and to some extent to himself.
When Lamoni began preaching all who would hear his words were converted, but some would not hear his words – in othe words, we are not talking about physical ability to hear.
All of this took place within a week of Ammon’s arrival in the land of Ishmael.
