When you encounter someone who seems to you to be extraordinarily beautiful, your first response is usually to think that they are an angel. Sometimes they are, but sometimes they are not. Angels of God who enter into the earth without being born often show none of the stresses of daily life. They are as beautiful as a newborn baby.
If they are not an angel, then they are probably someone who is sealed and raptured, and has become fully cleansed through urgent repentance. When you are fully cleansed, you also will be beautiful. When you are fully cleansed, you also will seem to be from a different world. When you are fully cleansed, and all of the millennial kingdom of God has become fully cleansed, the world at large will know that God himself is beautiful.
