And the speaker showed first what the temples of old times were; not places of meeting, as our churches to a great extent are, but dwelling-places, homes where God, or rather "the gods," were supposed to _live_. This idea was the one used as an illustration by St. Paul in the text, which means that _God_ has made all human hearts to be his home and dwelling-place, and that if we will let him, not barring the doors with sin and filling up the inside with other things, he will live there always; or, as our Lord Jesus says: "If any man will open unto me, I will come in unto him and will sup with him;" and in another place, "will abide with him." Then he explained so that the youngest of his audience could understand what are the sins that bar the door against our blessed Saviour, and how we set up idols upon the altars of God's temple, by worshiping dress, vanity, pride, revenge, worldliness, and our own way, and showed how nobody can really worship God and have him abiding in his holy temple who yields obedience to anything or cares for anything more than his will. He said it was an awful thing to _defile_ the temple of God by such things as drinking, smoking, and swearing, or even by evil thoughts and dishonest intentions, by selfish motives and unkindness in word or deed. He closed his sermon in these words:-- "My hearers, every one of you is a temple of the Holy Ghost, built and fashioned with exquisite skill, for his own chosen dwelling-place. See to it that ye defile not this temple, and if it be in any wise already defiled, from without or within, at once seek the double cleansing, which flows from the Cross on Calvary, that thus your sacred temple may be washed whiter than snow. Dethrone the idol _Self_ which has so long usurped the place of God upon its altar, and let him rule alone. And remember that every other human soul is likewise a sacred temple, no matter how defiled and degraded it has become by yielding itself willingly to the dominion of sin. Strive to do all that in you lies, by kind, persuasive words, by example and effort, to cleanse the degraded and polluted temples, and so do all in your power to exalt the dominion and worship of God in all the human souls which he has made." The impression made by this sermon upon its hearers was in accord with the character and religious development of each. James Mountjoy resolved to be more active and energetic in all efforts to improve the condition of his work-people, to raise the fallen, to reclaim the sinful, to set a better example and raise a higher standard of moral excellence, that the human temples over whom he had influence might be better fitted for the abiding presence of their heavenly Guest. Some of the more thoughtful of his boys resolved that smoking, drinking, and swearing should no longer, even in a slight degree, defile the "temples" entrusted to their keeping.
