If possible, and that depends on you, live at peace with everyone. not take revenge, my friends, but leave the punishment in the hands of God, for it is written: "Vengeance is mine, I will repay, saith the Lord.
Rather, "If your enemy is hungry, feed him, if he is thirsty, give him drink. By doing so, you will heap coals on his head."
Do not be overcome by evil, but overcome the evil with good. (Romans 12:18-21)
If possible, and that depends on you, live peaceably with all , interesting that this verse, Paul is very clear about what we will live often live in peace with other people does not depend on us, and that is why these recommendations are as valid at that time as today, nobody has said that the Christian life is easy and Many times we have had to live in the flesh, but simple at the same time, much as depends on us to live in peace with everyone, we are not called upon to interrupt the peace, but sometimes we feel violated, past to lead, we must act wisely, be obedient and live a life of blessing, to bless us but also those who may wish us harm, after all we are only doing what God asks.
Vengeance is mine saith the Lord, let him act on it, there will be times that seem silly, let us run over even by those who apparently are our brothers in Christ, but you know, trust the word and it says Vengeance is mine, let the Lord who exercises his justice is perfect, no matter what we do not for us, because we can be wrong.
Example we act for those who want to humiliate us, end up imposing our testimony, God calls us to act as Christians, not to get carried away by evil, by contrast, we overcome evil with good, if not, what is the difference with those who have not received?
