Many people hear this and say, “I’m sorry, I can’t give love if I don’t feel it! I can’t fake it. That’s too mechanical for me.” I can understand that reaction, but Paul doesn’t simply call us to a naked action; he also commands us to think as we act. “Husbands, love your wives just as Christ loved the church and gave himself up for her.”
This means we must say to ourselves something like this: “Well, when Jesus looked down from the cross, he didn’t think, ‘I am giving myself to you because you are so attractive to me.’ No, he was in agony, and he looked down at us—denying him, abandoning him, and betraying him—and in the greatest act of love in history, he stayed. He said, ‘Father, forgive them, they don’t know what they are doing.’ He loved us, not because we were lovely to him, but to make us lovely. That is why I am going to love my spouse.” Speak to your heart like that, and then fulfill the promises you made on your wedding day.
