Be not overcome of evil, but overcome evil with good. Christian maturity is not achieved by a so-called goodness, that holds badness merely in check. The Christian life is not badness stamped out, but crowded out. Error is overcome by truth.
Darkness is overcome by the light.
Hate is dispelled by love. Conflict in the Christian life is a problem for many. Some try forcing the will. But the will cannot be flogged into submission. We do not conquer our personal problems and our sin, by concentrating on them.
