The good news proclaimed at the Reformation in 1517 is still good news in 2017 and beyond.
Which is why the Reformation will never really be over, or a thing of the past.
From Michael Reeves on why the Reformation still matters:
Almost certainly, what confuses people into thinking that the Reformation is a bit of history we can move beyond is the idea that it was just a reaction to some problem of the day. But the closer one looks, the clearer it becomes: the Reformation was not principally a negative movement about moving away from Rome and its corruption; it was a positive movement, about moving toward the gospel. And that is precisely what preserves the validity of the Reformation for today. If the Reformation had been a mere reaction to a historical situation five hundred years ago, one would expect it to be over. But as a program to move ever closer to the gospel, it cannot be over.
