Mosiah 27:13 says "Nevertheless he cried again, saying: Alma, arise and stand forth,
for why persecutest thou the church of God? For the Lord hath said: This is my church,
and I will establish it; and nothing shall overthrow it, save it is the transgression
of my people"
If the gates of hell would not prevail against Christ's church, how could the
transgression of people overthrow it?
