Although I have devoted a large part of my life to the study of religion and to discussion with religious leaders of all faiths, I know very well that I cannot but seem presumptuous in writing about Jesus Christ and trying to explain what he means to me. I do so only because my Christian friends have told me, on more than a few occasions, that for the very reason I am not a Christian and that (I shall quote their words exactly) "I do not accept Christ in the bottom of my heart as the only Son of God,” it is impossible for me to understand the profound significance of his teachings, or to know and interpret the greatest source of spiritual strength that man has ever known.
