Have we ever needed Christianity more than we do today? It’s a rhetorical question, for sure, because the loss of our faith and the inability to confront Islam have never been greater. When I was a little boy during the war, my mother assured me that if I believed in Jesus everything would be OK. This was during the Allied bombing on Tatoi, the military airfield near our country house where the Germans concentrated their anti-aircraft guns. My Fräulein, the Prussian lady who brought me up, was more practical. She handed me a beautiful carved knife that made me feel safer than my prayers ever did.
