Indeed, the kingdom of God will grow on earth as the church creates an alternative society demonstrating what the world is not, but one day will be: Barth’s prescription of “a new sign which is radically dissimilar to [the world’s] own manner and which contradicts it in a way which is full of promise.”
From: [The Jesus I Never Knew]( by Philip Yancey 📚

I imagine this alternative society would look vastly different from what we see today.
