Once we see this we can react in two quite different ways. One way is the way of fatalism and indifference. The other way is the way of biblical faith. Just because life is but a breath and our days a passing shadow, every moment has eternal significance. Every moment is an opportunity for mirroring the truth of God.
Every moment is unique, pregnant, unrepeatable.
Every moment can be a window opening on the God who sends rain on just and unjust alike. What occurs in any moment can have consequences beyond anything we might imagine. I used to think this was so because of my social situation. If the American government raises interest rates tomorrow there will be huge consequences for every dimension of Canadian life. And the prime minister will have no control whatever over the move made by our American friends or over the consequences of it for Canadians.
