Exultation 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
