It is not enough for the Christian merely "to do nothing contrary to the law of love"; he must actively toil and suffer in its service, fighting to the death. His personal enemy he may and must forgive. Enemies have thus been won to the kingdom. The enemy of the weak and defenceless brother he must resist. The enemy of God's kingdom he must fight to the death. It is true that this foe of God is no human or visible foe. Our wrestling is not against flesh and blood; it is against the principalities and powers of darkness in the heavenly places. But we do not beat the air. This power of darkness finds incarnation in human form at least as readily as the Power of light. He fights with real and concrete weapons, and this reality is the ultimate test. For the foe who thus incarnates the evil power the Christian has no hatred as brother-man; only as agent of the evil power. The hatred ceases when the man renounces the evil allegiance. Hence the paradox of love that may necessitate a blow. Self-deception is here all too easy, but absolutely selfless devotion may be trusted even here not to substitute its own cause for God's. The very paragraph from which the non-resistants draw their doctrine has this conclusion: Wherefore seek ye _first_ the kingdom of God and his righteousness, and all these (outward blessings) shall be added unto you. It is because Jesus sought _first_ the kingdom, which means righteousness, peace and good will among men, sovereignty of right over might, overthrow of the powers of darkness which claim as their own the kingdoms of the world and the glory of them, that he could teach as the best means to its attainment forbearance and loving-kindness to the limit. For a limit there is--the _divine_ limit of the welfare of all. Loyalty to this ideal led Jesus to crown his sublime teaching with action sublimer still. When the scenes of his earlier ministry were closed, he left the quiet paths of teacher and healer in Galilee to tread the martyr's road, and to set up in his own cross an ensign to rally the scattered and bleeding flock of God. Because he sought "first the kingdom of God" Jesus held back his disciples from the bloody and disastrous path of Zealot fanaticism, and bade Peter return his futile sword to its sheath. For the same reason and no other he depicted to his disciples the Good Shepherd laying down his life in defence of the flock, and poured scorn upon the hireling who "when he seeth the wolf coming, leaveth the sheep and fleeth." It is for the same reason and no other that he also warned them of days to come when it should be the duty of the disciple unprovided with a sword to "sell his garment and buy one," days when only he that endured unto the end, fighting to the death against the powers of darkness, should be saved.
