(Red-letter portions of the New Testament)
Matthew 5:38-39, "You have heard that it was said, 'Eye for an eye and tooth for tooth.' But I tell you, 'Do not resist an evil person.'"
Jesus was not against law enforcement or citizen's stopping evil doers from inflicting violence on the innocent. He expected the proper authorities to reward good and punish evil. But on a personal level, He never sought personal justice for himself, though He never ceased to speak up for it for others.
Jesus was more concerned with compassion, than justice. He expected people to give each other more than justice, without squabbling over their own rights. Jesus would not join in our society's litigiousness. He expected people to make peace and settle out of court.
Rather than being consumed with suing His enemies for slander, He just went about His Father's business. He did not seek His own good, but the good of others. He sought the will of God, not clutching His own rights.
Constantly defending ourselves against unfair, even unjust treatment, and vindicating ourselves to others, distracts us from greater good and makes us petty and miserly.
If an evil person wants your stuff, give it to him. It is just stuff. God will deal with him. If an evil person treads on your rights, do not get side-tracked resisting him. Keep on doing God's will, however you can. If an evil person speaks evil of you falsely, do not be overly concerned with defending yourself. Continue about the Father's business and let your actions be your defense.
Our biggest troubles are not what unjust actions others take against us, but our own over-reactions. Retaliation is seldom rewarded by others, satisfying to ourselves, or pleasing to God. Jesus wants us to please God, not be consumed with vindicating ourselves.
