A Study of Exhortation - Vol. Do not be overcome by evil, but overcome evil with good. Here we come to the final verse of chapter 12. This verse sums up all that Paul has said since the fourteenth verse concerning living in a fallen world.
Evil often begets evil.
It is difficult not to consider retaliation when faced with evil. We must resist coming under the power of evil, being drawn into it. We must not even entertain thoughts of joining in evil or retaliation. Contrary to the world's belief, to retaliate is to lose. The world views the one who has the last blow or the last word as the victor.
