Since becoming a disciple of Christ, Paul knows that all mere orthodoxy, all mere knowledge concerning God’s will, is not only nothing but less than nothing. The more knowledge, the more obligation. The maintaining of revealed doctrine becomes blasphemy if it is not borne out by the corresponding testimony of the life. He who is always appealing to the Word of God without his life and conduct corresponding to this knowledge of God, dishonours God’s name, making Him an object of mockery and hatred. It is just those who know so well how to talk about God who make His name hateful among men, because their lives darken the picture of God and turn it into a caricature. The Lord is judged by the life of His servants; this is the truer, the more zealously they appeal to Him.
