In a little while the world will no longer see me, but you will see me; because I live, you also will live.
…if anyone is in Christ, there is a new creation: everything old has passed away; look, new things have come into being!
Then I saw a new heaven and a new earth, for the first heaven and the first earth had passed away, and the sea was no more.
And the one who was seated on the throne said, “See, I am making all things new.”
I’m guessing at the moment that this promise Jesus gave to his disciples the eve of his crucifixion concerns his resurrection and appearances to his disciples, though given the context, it might somehow refer to them seeing him after his ascension through the eyes of faith by the Holy Spirit. At any rate, one thing is certain. The new world through Christ’s resurrection was breaking into the old.
This old world is beaten down, and again and again repeats many of the same tragedies, seemingly in death throes, but it seems like it survives to see a new day and again do the same. It seems pushed to the brink of extinction, at least for the human species, and at least largely from what we can tell, humans at fault. And given world history, even in recent times, why should we be surprised?
But God enters in Christ, into the old creation, and brings in something new, yes nothing less than a new creation. And somehow we’re participants in that, even in this old world. We certainly groan with all of creation, awaiting the redemption of all things when the old will be no more (Romans 8). But we also experience inwardly this new life destined to continue now and forever in God’s new creative work in Christ (2 Corinthians 4, etc).
