Every true Christian will have control of his appetites and passions. Unless he is free from the bondage of appetite, he cannot be a true, obedient servant of Christ. The indulgence of appetite and passion blunts the effect of truth upon the heart. It is impossible for the spirit and power of the truth to sanctify a man, soul, body, and spirit, when he is controlled by sensual desires.
