But the LORD said to Samuel, “Do not look at his appearance or his stature, because I have rejected him. Man does not see what the LORD sees, for man sees what is visible, but the LORD sees the heart.” https://www.biblegateway.com/passage?search=1%20Samuel%2016%3A7&version=HCSB
It’s human nature. I once counseled a friend who was going through a tough time in his marriage. I asked him what was it about his wife that caused him to want to marry her. He said she was beautiful. I waited for him to share other qualities, inner qualities. Nope. Nothing. She was beautiful so he wanted to marry her. How many people have realized on their honeymoon that this physically beautiful person they just married has a not so beautiful heart?
It’s human nature. We make our judgments based on appearance too much of the time. Yet it’s not the externally attractive people that make a difference in our world. It’s those with beautiful hearts that are not rejected by God.
