God's righteousness is not the enemy of His mercy. His commitment to uphold the worth of His name does not cosign me to destruction, though I have besmeared His name by indifference and distrust. Rather, in the death of his Son, Jesus Christ, god conspired to vindicate his righteousness and justify sinners in one act. Which means His zeal to be glorified and His zeal to save sinners are one.
- John Piper, God's Passion for His Glory (Wheaton: Crossway Books, 1998).
