The article was vague about what R.C. Sproul said. I know many people who have benefited greatly from biblical counseling which I believe is very different from what this article is calling psychoheresy. We love to label things don't we?
Any therapy that suggests that man can heal himself is not biblical, but when a trained counselor can point you to Scripture and show you from God's word where your thinking is skewed is very helpful. We are to have Christ-esteem not self-esteem. Amen?
