The purpose of those who treat you wrongly is to cause you to develop a low esteem of yourself and this will eventually lead to self-destructive behaviour. The only way to respond to such individuals is to proceed with your life completely ignoring them.
Your continuous progress will liberate others who have been caught in their web of manipulation. The idea that no one can make progress without their approval. The Mark of the beast is really when a man sits as God in his temple demanding you bow down without which no progress.
You are the temple of God & 666 is the number of man. When a man wants to take the place of God in a person's life is when you come in contact with the mark of the beast. Don't self-destruct through anger and hate. Just walk away boldly and worship the Father asking for what next
