We may learn here, too, the true safeguard against specious errors. Paul thinks that he can best fortify these simple-minded disciples against all harmful teaching by exalting his Master and urging the inexhaustible significance of His person and message. To learn the full meaning and preciousness of Christ is to be armed against error. The positive truth concerning Him, by preoccupying mind and heart, guards beforehand against the most specious teachings. If you fill the coffer with gold, nobody will want, and there will be no room for, pinchbeck. A living grasp of Christ will keep us from being swept away by the current of prevailing popular opinion, which is always much more likely to be wrong than right, and is sure to be exaggerated and one-sided at the best. A personal consciousness of His power and sweetness will give an instinctive repugnance to teaching that would lower His dignity and debase His work. If He be the centre and anchorage of all our thoughts, we shall not be tempted to go elsewhere in search of the "treasures of wisdom and knowledge" which "are hid in Him." He who has found the one pearl of great price, needs no more to go seeking goodly pearls, but only day by day more completely to lose self, and give up all else, that he may win more and more of Christ his All. If we keep our hearts and minds in communion with our Lord, and have experience of His preciousness, that will preserve us from many a snare, will give us a wisdom beyond much logic, will solve for us many of the questions most hotly debated to-day, and will show us that many more are unimportant and uninteresting to us. And even if we should be led to wrong conclusions on some matters, "if we drink any deadly thing, it shall not hurt us." II. We see here the joy which blended with the anxiety of the solitary prisoner, and encouraged him to warn the Colossians against impending dangers to their faith.
