When your soul is turned within, it actually becomes separated from your external senses; and once your five senses are separated from your soul, they receive no more attention. Their life supply is cut off! They become powerless.
Two great advantages will come to you if you proceed in the way I have described. First of all, by withdrawing from outward objects, you will constantly draw nearer to God. The closer you are to God, the more you will receive His nature. The more you receive His nature, the more you will draw upon His sustaining power.
Second, the nearer you draw to the Lord, the farther you are removed from sin. So you see, simply by turning within to your spirit, you begin to acquire the habit of being near to the Lord and far from all else. These are the great rewards of turning your thoughts to Him—and Him alone.
