Unsettling the World (Luke 3:1-6)
Luke’s quoting of Isaiah isn’t meant to help us visualize a flatter, smoother world, or to help us to feel better about the hilly, bumpy world we live in. In this context John the Baptist’s call to repentance isn’t about trying to be more sincere about our remorse. It’s about shaking up the world as it’s currently situated, so that something new can be born.
In Luke’s hands these words are about tearing things up, about unsettling the way things are currently arranged. But this time around, what’s going to be disrupted, what’s going to be toppled aren’t hills and valleys in the wilderness that stand between Israel and home, but the powers and principalities that stand between God’s people and the future God has planned—between the way things are and the reign of God, the way things ought to be.
