Danger of a conquered foe
It is a remarkable fact, and is proved by Dr. Bell (in his History of British Insects), that the poison of the rattlesnake is even secreted after death. Dr. Bell, in his dissections of the rattlesnakes which have been dead many hours, has found that the poison continued to be secreted so fast as to require to be dried up occasionally with sponge or rag. The immoral author, like these rattlesnakes, not only poisons during his lifetime, but after death: because his books possess the subtle power of secreting the venom to a horrible degree. A moral sponge is constantly called into requisition to obliterate his poison for many years after he himself has been dead. (Scientific Illustrations.)
Revival of a conquered sin
As the bough of a tree bent from its usual course returns to its old position as soon as the force by which it had yielded is removed; so do men return to their old habits as soon as the motives, whether of interest or fear, which had influenced them, are done away. “Nature,” says Lord Bacon, “is often hidden, sometimes overcome, seldom extinguished. Let not a man trust his victory over his nature too far, for nature will lie buried a great time, and yet revive upon the occasion or temptation; like as it was with AEsop’s damsel, turned from a cat to a woman, who sat very demurely at the board’s end till a mouse ran before her.” The same philosopher gives the following admirable caution:--“A man’s nature runs either to herbs or weeds; therefore let him seasonably water the one and destroy the other.”
Need for watchfulness
None are so likely to maintain watchful guard over their hearts and lives as those who know the comfort of living in near communion with God. They feel their privilege and will fear losing it. They will dread failing from their high estate, and marring their own comfort by bringing clouds between themselves and Christ. He that goes on a journey with little money about him takes little thought of danger, and cares little how late he travels. He, on the contrary, that carries gold and jewels, will be a cautious traveller; he will look well to his roads, his horses, and his company, and run no risks. The fixed stars are those that tremble most. The man that most fully enjoys the light of God’s countenance, will be a man tremblingly afraid of losing its blessed consolations, and jealously fearful of doing anything to grieve the Holy Ghost. (Bp. Ryle.).
