While physical attraction is important when looking for a spouse, it is not most important. Instead of only focusing on physical attraction, we should focus on the true beauty of a person’s heart and character.
Of course, everyone wants to be attracted to the person they marry, and what's more, they want their spouse to find them attractive. Physical intimacy is a central part of marriage, and physical attraction plays a role in that. Physical beauty and desire are not just things that the world celebrates, but the Bible does, too. At the same time, the Bible puts these things into perspective. While the Bible acknowledges the good in taking care of our physical bodies and recognizes the physical attraction involved when looking for a spouse, it also emphasizes the importance of inner beauty. When looking for a spouse, we need to look at their heart and character, rather than prioritizing physical attraction. True beauty lies in godliness and a strong foundation in Christ, which will sustain your relationship through life's challenges
When looking for a spouse, your first concern should be his or her character rather than initial physical attraction. When looking for a spouse, your focus should be on the beauty of their heart and their godliness (or lack thereof). You need to find someone who will be a help when you experience tragedy and loss, someone who won't crumble under the pressures of life because they are standing on the rock of Jesus Christ. You aren't looking for someone who looks great next to you in photos; you are looking for someone who will be committed to Christ and to you. A person's heart and character are the source of true beauty, not their physical appearance.
Another danger of putting physical attraction too high on the list of what you are looking for in a spouse is that you might pass over some of the best people. You might miss the person who would be a wonderful father or mother, the person who you connect with on a deeper level than attraction, the person who would become your best friend, or the person you would enjoy the rest of your life with. This is not to say you should marry someone you don't find attractive just because he or she is a good person, but it is to say that attractiveness should not be top of your list of attributes to look for in a spouse.
