Jesus is no draughtsman of political blueprints, he is the one who vanquished evil through suffering. It looked as though evil had triumphed on the cross, but the real victory belonged to Jesus. And the cross is the only justification for the precept of non-violence, for it alone can kindle a faith in the victory over evil which will enable men to obey that precept. And only such obedience is blessed with the promise that we shall be partakers of Christ's victory as well as his sufferings.
