Said I: "Rather say: 'Lord, strengthen our flesh and our will!', for the strength of the memory always depends on the strength of the will. Your souls are quite willing indeed; but your flesh is weak, and thus also your memory, which only will become stronger later, once I have send the Holy Spirit to you. - However, now pay attention with the greatest concentration!" – The Great Gospel of John, Book 6, Chapter 229, Paragraph 13
