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.
