And how, it may be asked, can holiness be defined? As that purity of thought and heart which the Spirit alone can bestow; that abhorrence of sin which is something far higher than mere abstinence from sin. The man who bears the stamp of holiness, will detect and grieve over the lightest stain upon conscience; the coarse allusion, however witty, the drunkard's song, or the scoffer's jest, will never raise a smile on his lips: nor are they so likely to be heard in his presence; for the world, like Alexander, is often constrained to pay homage where holiness is legibly inscribed, and the silence of one whose habitual walk is with God, impresses more than the open rebuke of a more inconsistent believer. Deep reverence for God and God's Word is an accompaniment of "holiness unto the Lord;" the heavenly-minded Christian will not jest with sacred things, nor lightly use quotations from Scripture. It is the holy Christian, or to use the much abused, yet most expressive Scripture term, the "saint," who earnestly endeavours to "bring into captivity every thought to the obedience of Christ." How marvellous is that constant current of thought flowing through every mind, silently, secretly, like a narrow stream between banks so steep that we cannot catch a glimpse of its course, and can but trace it by the vegetation on either side, as our usual current of thought is judged of by our words and our actions! How often, when seated amongst silent companions—as, for instance, when travelling with strangers—have we reflected how interesting it would be, could we gain a glimpse of that stream of thought passing unceasingly through each brain; could we know whether it sparkles with hope, or "flows deeply and darkly" in shadow; whether it bears along golden grains of holy meditation, or mere bubbles of folly to break at a touch, or if the current be fetid and polluted with ideas that the lips would not dare for shame to form into words! Could the thoughts of the travellers in one railway-carriage, during a single hour of silence, be so photographed as to become visible to all, how marvellous would appear the difference between those of the worldling and those of the saint; though, alas! the musings of the holiest child of Adam would be found no pure and untainted stream, reflecting Heaven perfectly within its crystal depths.
