According to John Piper, the pursuit of pleasure in God is not merely permissible but essential. Drawing constantly on Scripture to build the case, he argues that seeking maximum joy is the way God is glorified, and that for the follower of Jesus there is finally no need to choose between duty and delight - delight is the duty.

Piper works out the implications across conversion, worship, love, Scripture, prayer, money, marriage, missions and suffering, which is what makes the book a whole theology of the Christian life rather than a single argument. It has altered how a generation thinks about relating to God. This is the Multnomah revised edition; an audiobook edition is also stocked.
