Context

“God cannot give us a happiness and peace apart from Himself, because it is not there. There is no such thing. That is the key to history. Terrific energy is expended—civilisations are built up—excellent institutions devised; but each time something goes wrong. Some fatal flaw always brings the selfish and cruel people to the top and it all slides back into misery and ruin. In fact, the machine conks. It seems to start up all right and runs a few yards, and then it breaks down. They are trying to run it on the wrong juice. That is what Satan has done to us humans. And what did God do?” source
