Karl Barth For Karl Barth , evil is the darkness that God passed over at the creation, but to which he allowed a certain provisional existence to prepare the way for a world transfigured by the light and truth of Jesus Christ. God did not create evil, he negates it and thus evil takes on a semblance of reality and power. Evil was already vanquished at the creation for the light of God's truth already encompassed the whole of the creation. The cross and the resurrection of Christ confirmed the conquest of evil, exposing the power of evil as having its basis in a lie. Evil is what God does not will rather than what he expressly sanctions.
Evil is the antithesis of good.
Evil has no future, it does not pose ultimate danger because God has already demonstrated his absolute sovereignty over the darkness. Barth does not offer a theodicy but the insight that evil escapes the sounds of rationality. Donald Bloesch concludes that theology cannot offer a fully satisfying explanation of evil, but it does point to a spiritual solution - the incarnation and atoning sacrifice of our Lord Jesus Christ. Something has gone radically wrong with creation, but God has acted to bring good out of evil. He has acted to reverse the work of the powers of darkness and disorder by himself becoming human flesh and dying on a cross, taking upon himself the retribution that we deserve because of sin.
