Bad theology dishonors God and hurts people. Churches that sever the root of truth may flourish for a season, but they will wither eventually or turn into something besides a Christian church.
John PiperGrace is not simply leniency when we have sinned. Grace is the enabling gift of God not to sin. Grace is power, not just pardon.
John PiperExultation that does not flow from education, affections that do not flow from knowing, savoring that does not flow from seeing, feeling that does not flow from thinking - are hollow and rootless - noisy gongs and clanging cymbals. And God is not glorified by artificial and empty passions. True delight is rooted in true doctrine. God-centered exultation is rooted in God-centered education.
John Piper
