Jesus' teaching in general [implies] that happy and fulfilling sexual relations in marriage depend on each partner aiming to give satisfaction to the other. If it is the joy of each to make the other happy, a hundred problems will be solved before they happen.
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 PiperIf you alter or obscure the Biblical portrait of God in order to attract converts, you don't get converts to God, you get converts to an illusion. This is not evangelism, but deception.
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
