Richard Foster is a Quaker theologian. Foster is best known for his 1978 book Celebration of Discipline, which examines the inward disciplines of prayer, fasting, meditation, and study in the Christian life, the outward disciplines of simplicity, solitude, submission, and service, and the corporate disciplines of confession, worship, guidance, and celebration. It has sold over one million copies. It was named by Christianity Today as one of the top ten books of the twentieth century. In the Celebration of Discipline, Foster said the following about Christian service.
Self-righteous service comes through human effort. True service comes from a relationship with the Lord.
Self-righteous service is impressed with the "big deal." True service finds it almost impossible to distinguish the small from the large service.
Self-righteous service requires external rewards. True service rests contented in hiddenness.
Self-righteous service is highly concerned about results. True service is free of the need to calculate results.
Self-righteous service picks and chooses whom to serve. True service is indiscriminate in its ministry.
Self-righteous service is affected by moods and whims. True service ministers simply and faithfully because there is a need.
Self-righteous service is temporary. True service is a life-style.
Self-righteous service is without sensitivity. It insists on meeting the need even when to do so would be destructive. True service can withhold the service as freely as perform it.
Self-righteous service fractures community. True service, on the other hand, builds community
