The two are in Los Angeles taping an appearance on the syndicated Twentieth Television show "Divorce Court," to be broadcast nationally April 1.
The show's presiding judge, Lynn Toler, is interviewing the couple about how their marriage survived after a male prostitute from Denver alleged a cash-for-sex relationship with Ted Haggard in November 2006, executive producer Mark Koberg said.
The scandal prompted Haggard to resign as president of the National Association of Evangelicals and New Life Church in Colorado Springs.
The Haggards say their marriage and Christian faith are stronger than ever, and they want people to know that divorce is not the answer.
"This is part of Ted's journey," Gayle Haggard said. "It's made him a better man. I see what has happened as a divine rescue."
She said she was helped through her darkest hours by the biblical principles of forgiveness, compassion and steadfastness, along with her husband's genuine repentance.
The couple will be paid an undisclosed amount for the interview, the latest in a series of public appearances that started in January when Ted Haggard began promoting an HBO documentary about his time in exile. He also has appeared on the "Oprah Winfrey Show" and "Larry King Live."
