A.W. Tozer emphasizes that mere knowledge of Christian doctrine is insufficient; true faith must be demonstrated through our daily lives. He points out that God desires us to act on our faith, just as He commanded Noah to do, rather than simply holding correct beliefs. Tozer agrees with Martin Lloyd-Jones that learning doctrine for its own sake can be perilous, and that doctrine should be lived out and incarnated in the lives of believers. The ultimate example of this is God Himself, who manifested His nature through His life on earth.

We know of many who have been deceived into believing that the learning and the memorizing of Christian doctrine is all-sufficient. They actually think that somehow they are better off for having learned the doctrines of religion. God actually asks of us what He asked of Noah long ago! "Demonstrate your faith in God in your everyday life!" It is evident that God did not say to Noah, "I am depending on you to hold the proper orthodox doctrines. Everything will be just fine if you stand up for the right doctrines." I have read a statement by Martin Lloyd-Jones, the English preacher and writer, in which he said: "It is perilously close to being sinful for any person to learn doctrine for doctrine's sake." I agree with his conclusion that doctrine is always best when it is incarnated-when it is seen fleshed out in the lives of godly men and women. Our God Himself appeared at His very best when He came into our world and lived in our flesh!
