The latest legal challenge to California's Prop 8 will unfold this week in a San Francisco courtroom.
On Thursday, a federal judge will consider a lawsuit that argues Prop 8 is illegal under the federal constitution, because it violates equal protection rights.
California voters approved the proposition last fall, effectively banning gay marriage in the Golden State.
Pastor Jim Garlow of San Diego was one of the original leaders of the petition drive to get Prop 8 on the ballot. He played a key role in organizing California churches to support the ballot initiative.
CBN News interviewed Garlow about gay activists' plans to challenge Prop 8 on the ballot in 2010 or 2012 and whether the church has the will to keep on fighting for traditional marriage.
"Wherever the government has a vested interest in supporting or validating same-sex relations or same-sex marriage they have an equal interest in quieting or silencing anyone who speaks against it because they make it a civil rights issue," he said.
Garlow said pastors are beginning to see that there is a lot at stake.
"I don't see that there's any evidence of giving up on the part of people for standing firm," he added. "What we're really trying to do is seize this moment to educate the younger voter. The younger voter, once they mature get married, have a baby, get a mortgage and inherently become more conservative. That works in our favor."
Garlow also talked about the importance of educating young voters.
"There's a lot of younger voters coming continually," he said. "So we're very aggressively, pro-actively targeting them on educating them on the issues. Because when they're educated they'll vote right."
Some religious liberties experts are urging gay rights groups in California to include religious exemptions in their efforts to legalize same-sex marriage. They believe such exemptions could appease Christian voters.
