Taking revenge on someone who has hurt us will satisfy our flesh but it is never productive. While the flesh is satisfied with "getting even" with another, our spirits suffer. Have you heard the bible passage, "Answer not a fool in his folly"? Take that truth and apply it with revenge as well. Take not revenge upon a foolish man in response to his evil actions.
Pay back not evil for evil. Why? Because you are not like that one who has harmed or offended you. So if you do take revenge on that one who has harmed you, basically you're doing what he has done - you are acting as he does.
I choose rather to please God and not pay back evil for evil.
Having said that, there are certain circumstances in which you must take action against another - Legally.
But we should know where that line is that other's may cross in which we must take action to protect ourselves from dangerous people. The law was made for the lawless. If you have to deal with a dangerous person, please utilize law enforcement, that is what they are there for.
There are many kinds of people in the world, Those who maliciously slander and harm others do these things because they care not for God nor man and woman that he created.
Vengeance is mine sayeth the Lord, I will repay
It is because I know God and trust him that I don't fret over those who have persecuted me. The schemes and plots of those who hate us are seen by him who sees all and is omniscient .
Why fear and fret over these people since God has your back? Friends, believe me, there is no reason to. Go to the Lord about those who torment and harm you. He knows already what they've done and what their plans are against you, but the main sign of a relationship is communication. This is why you are to tell father God your feelings and thoughts. This is prayer in it's purest form.
Other reasons why revenge is not the way to go:
Revenge will breed strife instead of ending it.
The bible instructs us to live our lives in quietness, not in backbiting, gossiping and in strife sowing.
Many time, those who persecute us are hoping we will react to their evil actions towards us-why give them the satisfaction?
Peace will never be gained by getting even.
The act of revenge sheds light on a "pride" problem, however large or small it may be.
Oneupmanship never births peace and quiet and humbleness, only strife and contention.
Don't get entangled in the ropes of revenge
Choose not to get entangled or caught up in some game of revenge.
I've known people whose lives were so empty that they've dedicated them to revenge and sowing strife at random.
With people like this, your only real choice is to have no contact with them.
Pray for them, but keep your distance.
Why are people like this?
Some of these people may have been members of a dysfunctional family.
They may not yet know how to treat others.
They are angry and resentful and only know how to hurt others.
They don't have God's love abiding with them because they've rejected it for whatever reason.
But here's the bottom line
You are not to behave as they do. You are not to lower yourself to their level and bring yourself to their playing field. You are not to play the games they do - games of revenge.
