Mosiah 27

I love the story of Alma and the sons of Mosiah. They were so wicked and tried to bring down the church, but even they could have a spiritual experience and a change of heart. They changed so much that instead of dragging down the church, they tried to make up for the damage they had previously done and became great missionaries for the church. So much so that "...they were instruments in the hands of God in bringing many to the knowledge of the truth, yea, to the knowledge of their Redeemer. And how blessed are they! For they did publish peace; they did publish good tidings of good; and they did declare unto the people that the Lord reigneth." (verses 36-37)
