In 1 Samuel 16:7, the Lord said that He, "does not look at the things people look at. People look at the outward appearance, but the Lord looks at the heart.”
I admit being guilty of this, especially with my neighbors. My hard confession is that I'm so bad with names that I called them the "hippy couple" until I was sure of their names. My wife has pointed out that I am very concerned about outward appearances. Part of the reason is self-consciousness because I know I'm overweight, balding, and wear store-bought teeth. In other words, age is kicking my butt and I've give anything to set the clock on my body about ten years ago. But G-d looks on my inside and that's where all believers need to focus on themselves and their neighbors.
