IF YOU ARE FELLING REVENGEFUL

in daily life, from public transport when we are kick whit elbow or a "lie" to us and we want to hit him back in the same way, unkind saleswoman at the kiosk, which should read the lesson; arrogant colleague at work that needs to be set in place; Head of whom we are very happy retorted when we feared for the job: and to the community in which we go, and throw as on the carpet someone for no reason, there is a sense of the need to take revenge for all the hits, unkind words, threats and criticisms, for we are sure that we did not deserve it.
Although it is not good, sometimes you just like to return the beating left you received, or to respond to an insult to a pungent replica. Sometimes you manage to refrain, sometimes not.
God understands this and our feelings. Of course, but they did not approve. Not because we would not know how, but rather because he knows that we go too far with a vengeance.
The question of revenge, it is mentioned at the very beginning of God's word, when Lamech, tenfold penalty which will take revenge for their wounds, compared to what God has ordained as an retaliation for Cain's wounds.
Instead of looking for revenge, God instructs us in the quest for love, because love is the greatest force that is an appropriate any situation, even one in which we want to take revenge. This is one of the most difficult tasks that we, as Christians, but not impossible, and God has not left us without guidance.
That is why we speak the word:
