Knowing is confirmed in showing. One cannot be complete without the other. (Paraphrase of Kip Cone, pastor-teacher)
Everyone would agree, probably, that knowledge is a good thing. After all, you have to know something in order to act. But as Cone points out, unless what you know is demonstrated in some fashion, it is incomplete. Knowing and doing are inseparable if one is to have personal fulfillment or to serve others well.
But whoever looks intently into the perfect law that gives freedom, and continues in it—not forgetting what they have heard, but doing it—they will be blessed in what they do (James 1:25).
