Now and then we see strange changes come over the once godly man—sometimes slowly, hardly to be discerned at the time, and sometimes with a strange rapidity. The man's character has changed, his personality has deteriorated. This may not be noted in any one particular thing, but the tone and atmosphere of his life is different. Speaking of an old student of his, occupying a position of importance in a distant city, a venerable college president once said to me after his last visit to this man, "There's something wrong." He could not see anything wrong. Just what it was he could not state; yet he was sure that there was something different, something wrong. Such a difference can be accounted for only by an internal change.
