The modern psychologist says, "Well, any idea like this is acquired." It must however be remembered that teaching has made this idea clear, but the God-ideal is the inborn tendency of man. The best explanation of the word God is to be found in the Persian word Khuda, because this is not only a name, but it is the meaning of the idea: it means selfrevealing. This itself shows that, if God is self-revealing, then man is not always depending upon the teaching of another; his natural longing is for God.
