I will simply let “The Doctor” speak for himself today. This has to be one of the most challenging quotes from him I have ever read:
“. . . The secret of the early Christians, the early Protestants, Puritans and Methodists was that they were taught about the love of Christ, and they became filled with a knowledge of it. Once a man has the love of Christ in his heart you need not train him to witness; he will do it. He will know the power, the constraint, the motive; everything is already there. It is a plain lie to suggest that people who regard this knowledge of the love of Christ as the supreme thing are useless, unhealthy mystics. The servants of God who have most adorned the life and the history of the Christian Church have always been men who have realized that this is the most important thing of all, and they have spent hours in prayer seeking His face and enjoying His love. The man who knows the love of Christ in his heart can do more in one hour than the busy type of man can do in a century. God forbid that we should ever make of activity an end in itself. Let us realize that the motive must come first, and that the motive must ever be the love of Christ.I end with the question which I asked at the beginning: To which of the circles do you belong? Are you pressing your way right into the centre? . . .
Are we pressing into the innermost circle? Are we seeking the Lord’s face? Are we coveting the knowledge of His love? The Apostle prayed for every single member of the Church at Ephesus that he or she ‘might be able to comprehend with all saints what is the length and breadth and depth and height, and to know the love of Christ, which passeth knowledge.’ How tragic it is that any of us should be living as paupers, out on the cold street, while the banqueting chamber is open and the feast prepared. Let us search for the knowledge of the Lord in the Scriptures and read about it in the lives of the saints throughout the centuries. As we do so, we shall never be content until we are in the innermost circle and looking into His blessed face.”
