Martin Luther- On Evil in the World

What he said nearly 500 years ago is just as true today:

When we were children, nothing disturbed us; we ourselves did indeed lead a more peaceful life, but the world has always been the same.

To be sure, it is true that in one era wickedness erupts more than in another, but this happens because different situations and greater opportunities exist for it to erupt; the wickedness of the world, however, always remains the same. Julius Caesar shook up the whole world because he had a great opportunity to do so; if Esau or Absalom had had such an opportunity, they would have done the same thing.

Therefore the evil in the world is always the same. See to it, then, that you have a peaceful and tranquil heart and that you do not get angry when you see this evil. You will never change the world, but see to it that you change into another kind of man.*
