But my mind was full of our conversation, and as I went on pondering over the matter, I thought that Yusuf might be right in his opinion as to the essence of God, for it seemed evident that the Creator of all beings ought to be perfectly simple; but I thought at the same time how impossible it would be for me, because the Christian religion had made a mistake, to accept the Turkish creed, which might perhaps have just a conception of God, but which caused me to smile when I recollected that the man who had given birth to it had been an arrant imposter. I had not the slightest idea, however, that Yusuf wished to make a convert of me. The third time I dined with him religion was again the subject of conversation. "Do you believe, dear father, that the religion of Mahomet is the only one in which salvation can be secured?" "No, my dear son, I am not certain of it, and no man can have such a certainty; but I am sure that the Christian religion is not the true one, because it cannot be universal." "Why not?" "Because there is neither bread nor wine to be found in three-fourths of the world. Observe that the precepts of the Koran can be followed everywhere." I did not know how to answer, and I would not equivocate. "If God cannot be matter," I said, "then He must be a spirit?" "We know what He is not but we do not know what He is: man cannot affirm that God is a spirit, because he can only realize the idea in an abstract manner. God immaterial; that is the extent of our knowledge and it can never be greater." I was reminded of Plato, who had said exactly the same an most certainly Yusuf never read Plato. He added that the existence of God could be useful only to those who did not entertain a doubt of that existence, and that, as a natural consequence, Atheists must be the most miserable of men. God has made in man His own image in order that, amongst all the animals created by Him, there should be one that can understand and confess the existence of the Creator. Without man, God would have no witness of His own glory, and man must therefore understand that his first and highest duty is to glorify God by practising justice and trusting to His providence. "Observe, my son, that God never abandons the man who, in the midst of misfortunes, falls down in prayer before Him, and that He often allows the wretch who has no faith in prayer to die miserably." "Yet we meet with Atheists who are fortunate and happy."
