“Within this Christian vision for marriage, here's what it means to fall in love. It is to look at another person and get a glimpse of the person God is creating, and to say, "I see who God is making you, and it excites me! I want to be part of that. I want to partner with you and God in the journey you are taking to his throne. And when we get there, I will look at your magnificence and say, 'I always knew you could be like this. I got glimpses of it on earth, but now look at you!'"
Elisabeth George once wrote that if you are married you should read 5 min. a day on marriage. So here are some great books on the topic.
