To preach the Gospel requires that the preacher should believe that he is sent to those whom he is addressing at the moment, because God has among them those whom He is at the moment calling; it requires that the speaker should expect a response.
“The things that have come into being change continually. The man with a good memory remembers nothing because he forgets nothing.”
“If you are going to try and hide something, sooner or later people are going to find out.”
