1 O that I were an angel, and could have the wish of mine heart, that I might go forth and speak with the atrump of God, with a voice to shake the earth, and cry repentance unto every people!
2 Yea, I would declare unto every soul, as with the voice of thunder, repentance and the plan of redemption, that they should repent and acome unto our God, that there might not be more sorrow upon all the face of the earth.
It's not his wish that is remarkable to me, but why Alma wished it - "that there might not be sorrow upon all the face of the earth." That wish for the elimination of sorrow is the mark of true charity, the pure love of Christ. God is love, and peace, and joy.
