The more faithful preachers are to the Word of God in their preaching, the more liable they are to the charge of hypocrisy. Why? Because the more faithful people are to the Word of God the higher the message is that they will preach. The higher the message, the further they will be from obeying themselves.
R. C. SproulFor the soul of a person to be inflamed with passion for the living God, that person's mind must first be informed about the character and will of God. There can be nothing in the heart that is not first in the mind. Though it is possible to have theology on the head without its piercing the soul, it cannot pierce the soul without first being grasped by the mind.
