"Today many people are attempting to use their mental capacity and logical thinking to obtain sanctification, yet this is nothing but a religious fabrication. They believe that if they just mentally put themselves on the altar and believe the altar provides the gift of sanctification, they can then logically conclude they are fully sanctified. Then they go happily on their way, expressing their flippant, theological babble about the “deep” things of God.
Yet the heartstrings of their old nature have not been broken, and their unyielding character, which they inherited from Adam, has not been ground to powder. Their soul has not throbbed with the lonely, gushing groans of Gethsemane. Having no scars from their death on Calvary, they will exhibit nothing of the soft, sweet, gentle, restful, victorious, overflowing and triumphant life that flows like a spring morning from an empty tomb."
