Napoleon Hill wrote, “You will never be greater than the thoughts that dominate your mind.” Many writers focus on one’s thoughts. They know the importance of mental attitude. The Bible agrees with this emphasis. However, the objectives and goals of the thoughts of the mind vary in the works of human writers. They usually seek material and temporary success. The Bible’s interest in the mind lies in becoming like Christ, in knowing God, and in reaching eternal life. See Colossians 3.1-4, for example. Such heavenly objectives open a chasm between human works and spiritual efforts.
