There is a saying that beauty is only skin deep,while ugly goes right to the bone.A beautiful person can be ugly on the inside, while an ugly person can be beautiful on the inside.God looks on the heart and HE knows if a person is good or evil,we can only look at the outside and we make our assessment on what we see,and we equate ugly with evil and beauty with good,not always the case though.Satan can appear beautiful while he is ugly and evil right to the bone.
