So what happens if you marry the gal of your dreams, pretty as a peach, and then she gets in a car accident and is horribly disfigured? You may have found her insightful, intelligent, with similar faith and goals, but then when you're staring at a face mared by burns and scars, what then? Will you forgo your vows and relationship because of her now appearance?
And what about the inevitable aging? What if her mind goes? So she's now wrinkly and saggy with faded eyes and a declining mental state?
Its important not to confuse attraction as a physical sensation vs. attraction as a mental sensation. Its like love and lust. You learn to be attracted to someone when you learn to love them.
Sure, physical attraction has its place, afterall, God made all those nice little hormones for a purpose. But it must be placed within its proper context, to place looks as a deal breaker is just assinine and unGodly.
Not to mention, there's the other niggling issue of "what is attractive?" Are you relying on society to determine what you think is attractive? The fake, plastic appearnce of women who have been photoshopped?
