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 PiperThe inner essence of worship is cherishing Christ as gain - indeed as more gain than all that life can offer - family, career, retirement, fame, food, friends. The essence of worship is experiencing Christ as gain. Or to use words that we love to use around here: it is savoring Christ, treasuring Christ, being satisfied with Christ.
John PiperLove is doing what will enthrall the beloved with the greatest and longest joy. What will enthrall the beloved this way is the glory of God. Love means doing all we can, at whatever cost to ourselves, to help people be enthralled with the glory of God. When they are, they are satisfied and God is glorified. Therefore loving people and glorifying God are one.
John PiperWhen the heart no longer feels the truth of hell, the gospel passes from good news to simply news
