There is a slender volume on prayer in my library, which I have never read properly so far as I know. I must have had it for more than fifty years. (It is in German and it is calledĀ Ich aber beteĀ by Alfred Christlieb.
At the beginning of the slender volume I am reading what an engineer said about the book:
He said that he has a borrowed book in his library, which he is only giving back with a heavy heart. He says, that he can hardly do without it.
I have started studying the book, and it is already a great blessing. And here is the title translated: But I am praying.
