Here is the message of Advent: faced with him who is the Last, the world will begin to shake.
Only when we do not cling to false securities will our eyes be able to see this Last One and get to the bottom of things.
Only then will we have the strength to overcome the terrors into which God has let the world sink. God uses these terrors to awaken us from sleep, as Paul says, and to show us that it is time to repent, time to change things.
It is time to say, “all right, it was night; but let that be over now and let us get ready for the day.”
We must do this with a decision that comes out of the very horrors we experience.
Because of this our decision will be unshakable even in uncertainty.
