“Listen to yourself speak, saying, “The knowledge of God has no practical application.” Do you know why all your Christian bookstores are filled up with self-help books, and five ways to do this or that, and six ways to be godly, and 10 ways not to fall?—because people don’t know God! And so they have to be given all sorts of trivial little devices of the flesh to keep them walking as sheep ought to walk! “Awake to righteousness, and sin not; for some have not the knowledge of God: I speak this to your shame” (1Co 15:34). Why the rampant sinning even among God’s people? It is a lack of the knowledge of God!”
