There are really only three possible players in our lives ~ God, us, and all other humans beings. (As for Satan, as long as we are aware of his existence and know God, he may be safely ignored since he just becomes a distraction, a small annoyance at times. He is dangerous only to those who do not believe that he exists.) We must respond to God alone and ignore all other fellow human beings, no matter what they do to us. What I mean is that we still take action following God's will, but we won't let their wrong doings in any way affect our love for God. If someone offends you, it's no different from a tree branch falling accidentally on top of you car ~ he will have to answer to God on his own in the end. You may picture that we are all linked to God upward individually, with no horizontal links between any two fellow human beings ~ a clean and simple image to remember.
