If someone offends you, turn the other cheek. If one looks like they have come from the world, love them. Be at peace with your brothers and sisters. Love them that hate you. If you can walk in this love, the love that I have taught, then you are my disciple. You can represent me and what I have taught. But do not pervert my doctrine. Hide your light if it does not illuminate my doctrine.
Yes, the doctrine of love, forgiveness and grace.
“Put on therefore, as the elect of God, holy and beloved, bowels of mercies, kindness, hunbleness of mind, meekness, longsuffering;
Forbearing one another, and forgiving one another, if any man have a quarrel against any: even as Christ forgave you, so also do you.”
