In late December 2004, over a quarter of a million people went about their routine without the slightest concern that a massive destructive wave of water was moving toward them. They surely would have hastily evacuated to higher ground if they had known that a wall of water was rushing toward them that would destroy whole cities and kill all in its path. But without warning, they went about their day's activities without concern for the approaching danger.

The gospel is the good word that wicked sinners can be reconciled to God through the redemption of Jesus. God's judgment is coming. His wrath is great and terrible. Yet as an act of grace, God has commissioned the saints to be His ambassadors to proclaim to the world – salvation is in Jesus who, for our sake, God made him to be sin who knew no sin, so that in him we might become the righteousness of God.
