The only way to accurately examine our profession of faith—the only dependable diagnostic—is scanning our profession with the light of the gospel: the message of what God has done to remove the cause of our being estranged from God—our sin. This is the heart of this passage and, at the heart of the heart is v. 21, where Paul writes one of the most profound verses in all of Scripture—what Calvin called “the wondrous exchange.” We consider three things about this exchange:

1. New Creation and the Wondrous Exchange (5:17)

2. Sovereign Reconciliation and the Wondrous Exchange (5:18–21)

3. Urgent Proclamation of the Wondrous Exchange (6:1–2)
