My blog post on Come Follow Me: Ether 12-15.

Excerpt:

Moroni begins his discourse on faith by telling us about Ether. Here, we see some important points regarding faith in Christ.  In reviewing them, we find:

First, he “could not be restrained because of the Spirit.” Other prophets have experienced such a power, such as Nephi and Abinadi. However, what seemed to be an occasional power for others seems to have been a continual and daily event for Ether. It may be due to the greater danger Ether found himself in, still it shows that God’s power can give great and constant power when the need arises.

God could give Ether great power, because Ether didn’t waiver in his faith nor in his efforts. Ether knew that great destruction would come upon the people, and there was only one thing that could save them temporally and spiritually.  Declaring repentance and faith in Christ was the only solution to the pandemic of sin.
