Believers in God have their billboards and now those who don't believe in God have their own message.
"We're not trying to attract people who believe in God. We're not trying to change their minds," said Terry McDonald with Metroplex Atheists.
At the weekly gathering of the Metroplex Atheists, the talk was about Monday's unveiling of two billboards with the message, "Don't believe in God? You are not alone."
"It's to let those people who don't believe know that they're not alone and that there are a lot of groups that they can become involved in," said McDonald.
The billboards will stand along I-35 near Loop 12 in Northwest Dallas and I-35 at Braswell in North Fort Worth.
The message encourages atheists and other non-believers to log onto www.dfwcor.org. The C.O.R stands for "Coalition of Reason." The website will be up and running Monday to coincide with the unveiling of both billboards.
Dr. Darrell Bock of the Dallas Theological Seminary welcomes the debate.
"They (non-believers) represent a significant minority in our culture. They're becoming more verbal and the thing to do is to have a conversation with them about that," he said.
Dr. Bock says the billboards may enrage some Christians at first, but he doesn't expect that anger to last.
"People pretty much have their minds made up on these kinds of matters. They're either going to be for or against," he said. "A lot of people will drive by and it will be the topic of conversation for a few days perhaps, but I don't think it's going to change very much."
Identical billboards are already up in Philadelphia and Denver. Non-believers have been gathering momentum as of late. HBO comic Bill Maher questioned God's existence in his 2008 documentary, "Religulous."
A recent study found that more than 15 percent of Americans no longer affiliate with a religion.
