Roger Olson:

Much of the blame for the rise of the “new Calvinism” is ours—Arminians. We have failed to provide our young people with our theology. So naturally they think Calvinism is the only biblical, evangelical theology when they encounter it preached and taught by attractive, persuasive, young men like Matt Chandler, Mark Driscoll, Louis Giglio, et al. And when they fall under the spell of John Piper who is simply a magician at persuasion.

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.

John Piper on preaching: The cross is also the ground of the humility of preaching because the cross is the power of God to crucify the pride of both preacher and congregation. In the New Testament the cross is not only a past place of objective substitution; it is also a present place of subjective execution-- the execution of my self-reliance and my love affair with the praise of man. "Far be it from me to boast except in the cross of our Lord Jesus Christ, by which the world has been crucified to me, and I to the world" (Gal. 6:14).

John Piper on Luke 13:1-5:

Some people came to Jesus and told him about the Galileans whose blood Pilate had mingled with their sacrifices. Jesus responded in shockingly unsentimental words: “Do you think that these Galileans were worse sinners than all the other Galileans, because they suffered in this way? No, I tell you; but unless you repent, you will all likewise perish.” In other words, Jesus says, “Are you amazed that few Galileans were killed by Pilate? What you ought to be amazed at is that all of you haven’t been killed, and that you will be someday if you don’t repent.”
