A voice says, “Cry!”
And I said, “What shall I cry?”
“All flesh is grass, and all its beauty is like the flower of the field.
Isaiah, the prophet of God, is instructed to raise a shout to God’s people. Isaiah follows by asking what the content of this shouting should be. And God tells him to prophesy to the people that “All flesh is grass”, in other words, proclaim the temporality of man.
In an American culture where the the enjoyment of life is found in its extension of youth (Live like you’re 20! Try this age-defying product!), the temporality, or the infiniteness-less, of man is not a welcome message. And so people run hard in this life for all the wrong reasons.
We “live for the moment” and invest everything in the one basket of this life as if there are no consequences to own up to. But God’s message to Isaiah is quite the opposite- You should run hard in this life because there are consequences to own up to.
And time is short, so get your act together and repent.
