"There is an [LDS] scripture that says to renounce war and proclaim peace," Boyack said. "But we think there is a lot of [Mormons] renouncing peace and proclaiming war."
The quote on the billboard references an article Kimball wrote for the church's Ensign magazine in June 1976, "The False Gods We Worship."
In the article, Kimball chastises church members who place worldly riches and desires before the gospel. He also claimed that people were too quick to clamor for war instead of proclaiming Christ's message of peace.
"When enemies rise up, we commit vast resources to the fabrication of gods of stone and steel ships, planes, missiles, fortifications and depend on them for protection and deliverance," Kimball wrote.
While Boyack has noted that GOP candidate Ron Paul has spoken out against war and been ridiculed for it and Mitt Romney has supported U.S. military actions, the billboard is not endorsing a particular candidate.
"We're looking to not change who gets elected, but change the minds of the electorate," Boyack said.
So far, he said he has received emails from people who agree and disagree with the message. And he's soliciting funds to keep the billboard up another month.
The billboard doesn't appear to be causing much political or spiritual strife.
Utah County Republican Chairman Dave Acheson said he hasn't seen the billboard, nor has anyone talked to him about it.
