Under this general rubric I could suggest many things, but let me deal with only one: its effects on the counselor. The counselor, who is worth his salt (a phrase that comes from a time when soldiers were paid in salt), will never fail to recognize the sin, habitual remnants of sin, and temptations that affect his own life as he deals with the same in others. If a man doing counseling isn’t warned over and over again of the possibilities for denying His God by a lifestyle that besmirches His Name, then he ought not be counseling. A counselor sees not only a wide variety of sin, but the tragic consequences of it. If he isn’t wise enough to learn from what he sees, he has no right counseling others.
A second benefit of biblical counseling is that to improve his counseling ability he is able to study the Bible as His guide. What a rich blessing! Contrast that with those, who in order to gain further information about their counseling, must study the wearisome works of psychologists. Not only are the concepts of such men frequently base and unedifying, but often even their language is disgusting. While a biblical counselor who studies regularly, in contrast, is afforded an opportunity to grow by grace through his biblical studies; the one who is not biblical fills his head and heart with the errors of men that can only be detrimental in their effects.
So, why not do biblical counseling? There is every advantage for a Christian himself, not to mention the benefits that his counselees derive from it. But, beyond that—think how the one glorifies God and the other glorifies man.
