(2) They had used his name not to promote his glory, but for their own selfish ends, money, honor, power, or social prominence. It is an enormous sin for an unconverted or blackslidden preacher to pervert to ambitious purposes that precious name which suggests amazing self-sacrifice, and in his personal character to misrepresent to the world the sinless Son of Man, the model by which we may become sons of God. This helps us understand why unbelief is the root and sum of all sins.
