The greatest problems Christianity has faced have been from within. Without we expect unbelief, denial, and even challenges. But wolves are never sheep. They are not interested in the good of the sheep, and if not recognized and challenged by those who are responsible for the flock will soon turn and devour. It is not without reason that Christians are called sheep in Scripture.
Sheep are helpless and have no natural defenses.
When predators sense the helplessness and panic of sheep, especially in confined quarters, they tend to kill repeat edly until the whole fold is destroyed. Exhausted by their killing spree, they sometimes leave the carcasses without so much as feeding on their kill. But fables may also refer to that which is good in its proper place and usage but which is easily abused by using it to detract from the Faith and the Word. Water is necessary and vital to life but we cannot overemphasize its importance to the exclusion of food. Likewise, when men take God's Word selectively and attribute to its parts an improper use, significance, or emphasis, it becomes falsified into the doctrines and commandments of men.
