If you heard in your heart that you were wrong, what were you wrong about? I haven't followed any of this, but perhaps what He was telling you what you were wrong in was HOW you were speaking. Were you reviling back when reviled? What I'm saying is maybe your behavior was wrong. If another child slaps you, your Father won't approve of the answer for you hitting back of: but he started it! No. He will say, but you are my child and you will not hit back, revile back or answer a slap with another slap.
Sometimes, what we are wrong about is in HOW we answer, not what we answer.
