There's a man in John 9 who keeps getting called back into the room. He's already answered their questions. He's already told them what happened. But the religious leaders keep pushing: because they don't like his answer.

What's remarkable isn't their hostility. It's his composure. He has nothing but what Jesus did for him, and that turns out to be enough. These leaders have Moses, the Law, the Scriptures, decades of study. And they're blind. He had nothing, but now he sees.

In John 9:26-29, we have a word of caution for all of us who've grown up in church, who can recite doctrine, who call ourselves Christians: knowledge about God is not the same as knowing God. Demons have good theology, but lack the one thing that matters: the saving work of Jesus applied to a dead heart by the sovereign grace of God. Sound doctrine should humble you, not make you prideful. Your boast is Christ alone.
