Thus the Apostle, in vv. 6 and 7, places this matter in the searching light of eternity. He brings to bear upon it one of the great spiritual maxims characteristic of his teaching. Paul's unique influence as a religious teacher lies in his mastery of principles of this kind, in the keenness of insight and the incomparable vigour with which he applies eternal truths to commonplace occurrences. The paltriness and vulgarity of these local broils and disaffections lend to his warning a more severe impressiveness. With what a startling and sobering force, one thinks, the rebuke of these verses must have fallen on the ears of the wrangling Galatians! How unspeakably mean their quarrels appear in the light of the solemn issues opening out before them! It was _God_ whom their folly had presumed to mock. It was the harvest of eternal life of which their factiousness threatened to defraud them. * * * * * The principle on which this warning rests is stated in terms that give it universal application: _Whatsoever a man soweth, that shall he also reap_. This is in fact the postulate of all moral responsibility. It asserts the continuity of personal existence, the connection of cause and effect in human character. It makes man the master of his own destiny. It declares that his future doom hangs upon his present choice, and is in truth its evolution and consummation. The twofold lot of "corruption" or "life eternal" is in every case no more, and no less, than the proper harvest of the kind of sowing practised here and now. The use made of our seed-time determines exactly, and with a moral certainty greater even than that which rules in the natural field, what kind of fruitage our immortality will render. This great axiom deserves to be looked at in its broadest aspect. It involves the following considerations:-- I. _Our present life is the seed-time of an eternal harvest._
