Essentially, in about 15-20 years or so, when the Boomer generation is set to recede from the scene, we are going to see a massive demographic shift that will impact (a) raw numbers, (b) culture and institutional knowledge, forms, and leadership, and (c) pure dollars coming into fund the ministry of the church.

Connected to this, I want to add a related phenomena: the massive dechurching of America and the obsolescence of American religion. I won’t rehash this at length, but most of you have heard the stats from Ryan Burge, Michael Graham, and Jim Davis, or heard a podcast about Christian Smith’s work on the obsolescence of religion. In the last 25 years, 40 million people stopped going to church—and actually, Graham and Burge’s new book argues that it’s closer to 60 million. Beyond that, traditional religion has continually lost market share, not to atheism, but general non-traditional spiritualism, or nothing in particular.

I’ll say that, briefly, the Vibe Shift is very real, but the Quiet Revival basically has no data for it. On the ground, things have shifted politically, and I think even created an openness to spiritual conversations broadly among the younger generation and, yes especially among young men. That said, statistically speaking, there is no data telling us that we should be banking on any kind of quiet revival to come save us.

I can't capture the entire spirit of the essay here, and I have no connections to the PCA, but this description feels like an accurate summarization of the most likely future. I kinda wish we could put a memoriam on using the world "revival" for a minute. We need a better way of being optimistic while simultaneously being realistic.
