"Every moment and every situation challenges us to action and to obedience.
We have literally no time to sit down and ask ourselves whether so-and-so is our neighbor or not. We must get into action and obey — we must behave like a neighbor to him.
But perhaps this shocks you.
Perhaps you still think you ought to think out beforehand and know what you ought to do. To that, there is only one answer. You can only know and think about it by actually doing it. It is no use asking questions; for it is only through obedience that you come to learn the truth."
