What the Bible says about Study, Excessive
(From Forerunner Commentary)
Studying a specific theological subject for months and years will make a person unbalanced, emotionally attached to the topic, and deficient in the weightier matters of God's way of life. Such persons become gluttons for new ideas that feed heresy, and they justify their over-consumption by claiming that it is not their fault that they have access to so much religious information over the Internet and through the mail.
"Much study"—especially of a trivial subject or one unrelated to salvation—"is wearisome to the flesh," writes Solomon (Ecclesiastes 12:12). People of this inclination, the apostle Paul says, are "always learning and never able to come to the knowledge of the truth" (II Timothy 3:7). Just as with food, excessive study of the same subject day-in and day-out can cause a person to be unbalanced. We have to know when to say, "Enough!"
