John Piper on the cross of Christ:
Even though all scorn the glory of God, and even though God’s righteousness is his unwavering commitment to uphold [His] glory– nevertheless, God designed a way to vindicate the worth of his glory and at the same time give hope to sinners who have scorned that glory– and what he designed was the death of his Son. It took the infinitely costly death of the Son of God to repair the dishonor that my pride has brought upon the glory of God.
It horribly skews the meaning of the cross when contemporary prophets of self-esteem say that the cross is a witness to my infinite worth, since God was willing to pay such a high price to get me. The biblical perspective is that the cross is a witness to the infinite worth of God’s glory and a witness to the immensity of the sin of my pride. What should shock us is that we have brought such contempt upon the worth of God that the very death of his Son is required to vindicate that worth. The cross witnesses to the infinite worth of God and the infinite outrage of sin.
