It seems from my experience (and from what I have heard others say) that possibly the most neglected and underappreciated gift of the Spirit is the gift of discernment. Tim Alberta, himself the son of a pastor, cites Michigan pastor Ken Brown, writing, “'Discernment'—one’s basic ability to separate truth from untruth—'is a core biblical discipline. And many Christians are not practicing it.'”
Now I'm not talking about so-called "discernment ministries" that seem to do nothing more than pick out certain individuals, churches, ministries, or movements as "enemies of the faith" and then go over everything those people say or do with a fine-toothed comb to find the smallest mistake they can use to raise a charge of "HERESY!!" I'm talking about real, Spirit-guided thinking.
