The Human Rights Campaign (HRC), the nation's largest LGBT rights advocate, has launched a TV campaign promoting gay rights in the Deep South.

The campaign, titled All God's Children, is a first for the Deep South.

A television ad featuring a conservative Christian Republican mother will begins airing Monday in Jackson, Mississippi.

In the 60-second spot, Mary Jane Kennedy says that she was unprepared for learning that her son is gay.

“I said, 'What is going to happen? This is going to tear our family apart. Your daddy will die,'” she said. Instead, Kennedy said, her husband cried and said he loved his son.

“God called us to love each other,” Kennedy added. (The video is embedded on this page. Visit our video library for more videos.)

The multifaceted campaign – it will also include direct-mail, billboards and online banner ads – will last four weeks and cost $310,000.

Depending on the response in Mississippi, the campaign may extended to Alabama and Arkansas.

“This first ever campaign in the Deep South is an unprecedented opportunity to tell the true stories of LGBT Mississippians – stories of hope, family, perseverance and progress,” HRC President Chad Griffin said in a statement. “LGBT people are just like everyone else – they go to church, volunteer in their communities, and want to build a better future for their families. Most importantly, they're born and raised in the state of Mississippi, and they want to help make it a more inclusive place to live for everybody.”

According to a Gallup poll, 61 percent of Mississippians say that they are very religious, making the state the most religious in the U.S.

The commercials will begin airing the same week that a federal judge will hear arguments in a lawsuit challenging Mississippi's ban on gay marriage, overwhelmingly approved by voters a decade ago.
