It is a temptation which in many varying forms has always beset human life. No small part of the danger is that this evil, above all others, grows in silence, and yet seems to be aggravated by publicity. The preacher cannot speak plainly about it, and even writers shrink from touching the subject. We can, however, be thankful that the book, which is God's book rather than man's, knows nothing of our false modesty and conventional delicacy: it speaks out not only boldly, but minutely; it is so explicit that no man who with a prayerful heart will meditate upon its teachings need fall into the pitfall--that pitfall which seems to grow even more subtle and more seductive as civilization advances, and as the great cities absorb a larger proportion of the population; or if he fall he can only admit with shame and remorse, "I have hated instruction, and my heart despised reproof. Neither have I obeyed the voice of my teachers, nor inclined mine ear to them that instructed me. I was well-nigh in all evil in the midst of the congregation and assembly."[20] In the second place, we must try to look at these temptations in the light of our own day, in order that we may listen to the voice of wisdom, not in the antiquarian, but rather in the practical spirit. The second temptation exists amongst us almost unchanged, except that the vast accumulation and concentration of vice in great cities has provided that mournful band of women whom a great moralist has designated the Vestal Virgins of Humanity, consecrated to shame and ruin in order to preserve unsullied the sacred flame of the domestic altar. The result of this terrible development in evil is that the deadly sin has become safer for the sinner, and in certain circles of society has become recognized as at any rate a venial fault, if not an innocent necessity. It is well to read these chapters again with our eye on the modern evil, and to let the voice of Wisdom instruct us that the life is not the less blighted because the body remains unpunished, and vice is not the less vicious because, instead of ruining others for its gratification, it feeds only on those who are already ruined. If the Wisdom of the Old Testament is obscure on this point, the Wisdom of the New Testament gives no uncertain sound. Interpreting the doctrine of our book, as Christians are bound to do, by the light of Christ, we can be left in no doubt that to all forms of impurity applies the one principle which is here applied to a specific form: "He doeth it that would destroy his own soul." "His own iniquities shall take the wicked, and he shall be holden with the cords of his sin."[21]
