What is the Church? If we want to minister to today's broken world we need to understand what Scripture means by the Church. New Testament writes about the body of Christ and the Kingdom of God. For the writer to the Hebrews, the Church of today finds its most proper definition in terms of the historical experience of the old covenant people of God "in the wilderness" during the days of Moses. For him, the Church God's people in the wilderness. His unifying perspective on this vital question of the Church's self-definition provides fresh insight into the nature of the Church--an insight that has the promise of reviving and redefining the life of Christ's people even today. Rooted in the redemptive experience of the old covenant people of God, this life-shaping self-definition may provide much-needed aid to the confused state of churches in Christ for the 21st century. Palmer Robertson will help us consider the nature and mission of the people of God in today's world as defined by Hebrews.
