Warren’s observation is sharp and uncomfortable: “Some of the most carnal Christians I’ve known were a veritable storehouse of biblical knowledge.” Theological knowledge, accumulated without corresponding character formation, does not produce maturity. It produces pride. Paul’s own statement clarifies this: “Knowledge puffs up, but love builds up” (1 Cor. 8:1).
The failure mode is widespread: churches measure discipleship by quiz scores, doctrinal accuracy, or the ability to cite verses. A person who can explain systematic theology but who is harsh, self-righteous, and relationally destructive is not mature — they are more dangerous for having the vocabulary to justify themselves.
The fruit-based measurement (Matthew 7:16) is the actual standard: by their fruits you will recognize them. Character, demonstrated in behavior, in how someone treats people they disagree with, how they handle failure, how they love the difficult person — this is the evidence of spiritual growth.
Warren’s five levels of spiritual learning — knowledge, perspective, conviction, skills, and character — are all needed, but they have an order and a destination. Knowledge is the starting point, not the arrival. Character is the destination. The entire process serves character formation: learning to be someone, not just to know things.
For discipleship structures at MNFC: the diagnostic question for mature members is not “what do they know about Divine Principle” but “what kind of person are they becoming?”
