What is it like to fall in love? For someone, like me, who's never fallen in love, this is a difficult question to answer. However, I believe this is one of the reasons God has granted us with an imagination. When you fall in love, you want to do anything for the other person. You're willing to die for the other person. You would change for the other person. You want to know the other person even more (you can never learn enough). You want to spend time with the other person learning this person's likes/dislikes, friends, family, etc.
With all this in mind, why should the idea of Christianity being "More Like Falling In Love" seem so wrong? In fact, the entire Bible tells the story of God wooing His people back to Him. He did this by sending His one and only Son to die for us. If this isn't love, I don't know what is.
