In Matthew 10:28, Jesus told his disciples: “Do not be afraid of those who kill the body but cannot kill the soul. Rather be afraid of the One who can destroy both soul and body in hell.” In other words, the one with the power to sentence body and soul to eternal damnation is God. If you are going to be afraid of anyone, it should be Him.
Question: Why is it then, that so many Christians would sooner trust an unlearned pastor with the supreme task of watching over and giving an account for their souls (Hebrews 13:7), than they would a doctor with no formal education, but who happens to be really good in biology?
A.W. Pink has something to say about these kinds of shepherds and their preaching.
“It is because so many untaught men, unregenerate men, now occupy the pulpits that “another gospel” (Gal. 1:6) is being so widely and generally disseminated. Multitudes who have neither “tasted that the Lord is gracious” nor have “the fear of the Lord” in them, have from various motives and considerations invaded the sacred calling of the ministry and out of the abundance of their corrupt hearts they speak. Being blind themselves, they lead the blind into the ditch. Having no love for the Shepherd they have none for the sheep, being but “hirelings.” They are themselves “of the world” and therefore “the world heareth them” (1 John 4:5), for they preach that which is acceptable unto fallen human nature and as like attracts like, they gather around themselves a company of admirers who flatter and support them. They will bring in just enough of God’s Truth to deceive the unwary and give an appearance of orthodoxy to their message, but not sufficient of the Truth, especially the searching portions thereof, to render their hearers uncomfortable by destroying their false peace. They will name Christ but not preach Him, mention the Gospel but not expound it.”
