"We're going to give it a try," said the Rev. Ed Young, who has four children with his wife of 26 years.
Young, 47, said he believes society promotes promiscuity and he wants to reclaim sex for married couples. Sex should be a nurturing, spiritual act that strengthens marriages, he said.
"God says sex should be between a married man and a woman," Young said. "I think it's one of the greatest things you can do for your kids because so goes the marriage, so goes the family."
Young said he will deliver his seven-day sex challenge while sitting on a bed in front of his Dallas-area church campus.
He is founder of the nondenominational Fellowship Church, which draws about 20,000 people each Sunday and also has campuses in Fort Worth, Plano and Miami.
Earlier this year, a southwest Florida pastor, perhaps having more faith in his congregants' stamina, issued a 30-day sex challenge.
