Paul's counsel to the congregation in Rome (Romans 12:17-20; 13:8-10) is clearly in line with what Jesus taught. He insists that we must never allow vindictiveness, the desire to get even with someone for a suffered wrong, to drive us.
In the same vein, Peter taught that we must not repay evil with evil, insult with insult, but we must bless (I Peter 3:8-9). Why are we called to react this way? Because if we want to be in God's Kingdom, it can only happen without the spirit of murder dwelling in us, and those evil retaliations are the spirit of murder. We are not to take vengeance because God has retained that responsibility to Himself. Is that not the way it should be? Only He fully knows and understands every facet of the circumstances and can judge perfectly. By the way, Paul addresses the issue of retaliation four times in Romans 12, which begins by stating that we are to be living sacrifices and not to conform to this world's ways.
The picture should be clear. Somebody must be willing to do this if there will be peace. Jesus set the example: He, refusing to strike back, died for the entire world. Christ's non-retaliatory remedy is ultimately for everybody's benefit, but until He returns, the standards He set can be met and lived only by those who, like Jesus, have the Spirit of God, are living by faith, and are enabled to keep God's ways by God Himself.
