God is shaking the world. Not just with earthquakes, but through events, trials, and the passing of kingdoms. Why? So that only what cannot be shaken remains - God's kingdom. Our response must be gratitude and reverence.

1. God's holiness shows how serious sin is (v. 18-21).

2. Jesus brings us into God's presence (v. 22-24)

3. God's kingdom cannot be shaken (v. 25-29)
