There is a general belief that God does hear the pure Christian more readily than he does the vile reprobate. That belief is founded in the moral laws universally recognized in human relations. There may also be a semiscientific reason. The soul which is in tune with the Infinite can more effectively detect and understand the "sound waves" from the spirit world than the soul which is out of tune with God. In the mass of the correspondence about which this book is written there are strong testimonies to the necessity and attainableness of a practical harmony with the Spirit of God. One man who has been long a teacher of psychology wrote that he had made a deliberate test of the matter, and a condensed report of his experience is here given. He sought "to place his soul in communion with God." He desired that state of spiritual harmony with the divine character which would make him sensitive to every spiritually divine impression. Hence, he prepared himself in this way: he locked himself in his room and gave himself up to the serious business of getting into communication with God. He began to count his sins of commission and earnestly asking forgiveness; he promised the Lord that he would guard himself against them evermore. He then tried to comprehend the awful list of sins of omission which for a while made him hopeless of God's favor. But in deep and prayerful meditation, thinking long on the great mercy of God and of the propitiation Christ had given, he felt his soul slowly emerge from the slough of despond. Suddenly a strange confidence took possession of his soul and a feeling of glad triumph overcame all doubt of his forgiveness. The assurance that he was getting into harmony with the Spirit of God became complete. He threw himself across his bed and "let go of himself," making an absolute surrender to the spiritual impressions.
