In his recent book The Mission of God, Christopher Wright wrote,
"This worldview, constituted by putting the mission of God at the very center of our existence, is disturbingly subversive and it uncomfortably relativizes one’s own place in the great scheme of things. It is certainly a very healthy corrective to the egocentric obsession of much Western culture – including, sadly, even Western Christian culture. It constantly forces us to open our eyes to the big picture, rather than shelter in the cozy narcissism of our own small worlds." (534)
Wright describes both the challenge facing discipleship and the solution: an "egocentric" culture that manifests itself in individualism, consumerism, and materialism; and a worldview that puts "the mission of God at the very center of our existence." As the core of discipleship content, this missional worldview is necessary for shaping a people out of Western culture and into the kingdom of God, a community of generous and sacrificial love.
