The agonizing message to a young Christian couple in love: Sex can wait, but so can marriage.

“It’s unreasonable to say, ‘Don’t do anything … and wait until you have degrees and you’re in your 30s to get married,'” said Margie Zumbrun, who did wait for sex, and married Stephen fresh out of Purdue University. “I think that’s just inviting people to have sex and feel like they’re bad people for doing it.”

Against that backdrop, a number of evangelicals are promoting marrying earlier, nudging young adults toward the altar even as many of their peers and parents are holding them back.
