One challenging phrase was quoted incidentally, however, at 3 events I attended. It is one description, by Martin Luther, of what it means to have real faith:
Auch wenn ich wüsste,Which being translated means
dass morgen die Welt zugrunde geht,
würde ich heute noch
einen Apfelbaum pflanzen.
Even if I knew that the whole world
was going to smash tomorrow,
Still, I would plant an Apple Tree today.
