It is not enough to interpret these words as meaning that our Lord's purpose indeed was to bring peace, but that the result of His coming was strife. The ultimate purpose is peace; but an immediate purpose is conflict, as the only road to the peace. He is first King of righteousness, and after that also King of peace. But, if His kingdom be righteousness, purity, love, then unrighteousness, filthiness, and selfishness will fight against it for their lives. The ultimate purpose of Christ's coming is to transform the world into the likeness of heaven; and all in the world which hates such likeness is embattled against Him. He saw realities, and knew men's hearts, and was under no illusion, such as many an ardent reformer has cherished, that the fair form of truth need only be shown to men, and they will take her to their hearts. Incessant struggle is the law for the individual and for society till Christ's purpose for both is realised.
That conflict ranges the dearest in opposite ranks. The gospel is the great solvent. As when a substance is brought into contact with some chemical compound, which has greater affinity for one of its elements than the other element has, the old combination is dissolved, and a new and more stable one is formed, so Christianity analyses and destroys in order to synthesis and construction. In Matt. 10:21 our Lord had foretold that brother should deliver up brother to death. Here the severance is considered from the opposite side. The persons who are set at variance' with their kindred are here Christians. Perhaps it is fanciful to observe that they are all junior members of families, as if the young would be more likely to flock to the new light. But however that may be, the separation is mutual, but the hate is all on one side. The man's foes' are of his own household; but he is not their foe, though he be parted from them.
