I don't think ONLY Jesus is important in a relationship. I agree it's most important. But you can love someone, be best buds, and not make suitable living companions. Two people with incompatible personalities or opposite living preferences can fall in love. This makes sense, because if love was all you needed for a successful relationship, you probably would've married your first boy/girlfriend.
That's why the first question my pastor asked David and I after we were engaged was "Why do you want to get married BESIDES that you love each other?" Neither of us was taken aback or caught off guard and was able to answer right away. You can't live on love, even a mutal love for God, there HAS to be more. That's where learning to love comes in - learning to love despite not getting what you want.
I have always liked a more stocky build, tall or not, dark hair, and a little facial hair. I have dated light haired men; I have dated skinny men. So while I like certain things, I will bend. I always wanted a deeply theological, liberal arts inclined mind. My husband is not interested much in detailed theology though he can carry on a conversation about it, and he is far more technical minded than abstract. But you know what? I think that's good because we compliment and learn from one another. Iron sharpens iron.
I used to want someone that agreed with everything I thought theological as well as other opinions, or very close. How boring would that be? What would we talk about? We have many of the same sentiments, esp in what I think are key areas to be in agreement on. But we do disagree on some major topics and since we are able to talk without being adversarial of what we don't like, we learn new things from one another and we challenge one another to think in new ways. I think that's healthy and good for a relationship.
I have to disagree just a little bit. I agree that Jesus shouldn't be the only thing. There has to be chemistry. Otherwise, you're just two friends at best fooling each other (I know husbands and wives are supposed to be best friends, but I think you get what I'm saying). If one person loves being outdoors while the other likes being a hermit, I would think there would be some issues. But as far as physical appearances, I personally believe they don't matter, as most of the time, we can't control them. Now we're not to be sitting on the couch watching daytime tv eating a bag of chips every day, but other than that I think Jesus fits all the criteria. Because if it's meant to be, everything else will come with Him.
