again if we give them welcome. If we cherish base and evil thoughts, they will soon fill the treasure house of the heart. If , on the other hand, we cherish lofty thoughts, if we act from noble motives, these will fill our hearts and determine the issues of our lives. It is necessary for us to be on our guard against that sophistry which the heart too often practices upon itself. It is easy to fall into the habit of inventing fair names for foul motives, fair reason, for foul projects. At first, we stand back, terrified at the hid eousness of our sins ; but by assigning fair names and reason to our evil actions, we at last become unable to judge the moral quality of our conduct. We thus deceive ourselves. At first we are unwilling to look into our hearts, and at last we become unable to see their real blackness. In conclusion, Dr. Schaeffer emphasized the importance and the duty of keeping the heart pure and whole ; and to this end he urged upon his hearers the great value and need of devotion and of the religious life.
