A physical attraction can vanish when that figure 8 body vanish, When that long hair vanish, and when the things you can do for them vanishes. A physical attraction is not meant to last. One must love a person despite their short comings. One must see the heart and the mind of another. A relationship is like a tree. It has to be rooted properly in order for it to stand strong.
A spiritual connection is better than a physical attraction, because a spirit is omnipresent vs something physical that's not. A person who loves you, should love you whether you're around or not. A person who believes in Christ understands the commitment to you as it relates to their commitment to Christ. Doesn't mean they're not human and won't make mistakes, but compared to someone who doesn't believe in Christ are more conscious of there decisions.
A person seeking a spiritual connection with you is not looking for the beauty you possess on the outside. They're more in tuned with your inner beauty. They're not looking to see what you can do for them, but what they can do for you. When your physical appearance begins to fade away, that person who has that spiritual connection with you will not. We are not of our own. We must seek salvation and do things that's pleasing to God not man. While looking for love, be sure to include God in the midst. With man nothing is possible. With God, all things are possible. Be connected!
