Kuzari

 Kuzari (01:14) Al Khazari: Exactly so; but the human mind cannot believe that God has intercourse with man, except by a miracle which changes the nature of things. He then recognizes that to do so He alone is capable who created them from nought. It must also have taken place in the presence of great multitudes, who saw it distinctly, and did not learn it from reports and traditions. Even then they must examine the matter carefully and repeatedly, so that no suspicion of imagination or magic can enter their minds. Then it is possible that the mind may grasp this extraordinary matter, viz. that the Creator of this world and the next, of the heavens and lights, should hold intercourse with this contemptible piece of clay, I mean man, speak to him, and fulfill his wishes and desires.
