Before Piper tells us how to live, he insists we understand *why* — and the answer is the cross of Jesus Christ, which he calls the blazing center of God's glory. Let these questions help you feel the weight of that claim.
Discussion Questions
7 questions1.Piper argues that the cross is not merely the means of our forgiveness but the supreme display of God's glory — simultaneously revealing His justice and His love in a way nothing else could. How does this expand your usual way of thinking about what happened at Calvary?
2.He draws on Romans 3:25–26 to show that God's gift of Christ as a propitiation was designed to 'demonstrate his righteousness' — that the cross was not God setting aside His justice but *satisfying* it. Why does this distinction matter for how we understand the gospel?
3.Piper uses Paul's declaration in Galatians 6:14 — 'May I never boast except in the cross of our Lord Jesus Christ' — as the foundation for a life that doesn't waste itself. What does it look like practically to 'boast in the cross'? What does it *not* look like?
