terrible advice for marriage

"sometimes when [people] say marriage is a partnership, they make it sound like a business arrangement. “You need to give fifty-fifty,” they might say. But this is terrible advice. It is worldly advice. It does not reflect the reality of marriage, which is a reflection of the unique reality of the gospel. After all, Jesus Christ did not say to sinners in need of redemption, “Meet me halfway. Let’s go fifty-fifty on this deal.”... It’s not fifty-fifty; it’s one hundred–one hundred. At any given time either spouse won’t have 100 percent to give, but this does not diminish the other’s commitment because they are not in a contract but a covenant."
