Ed Clowney on the Mission of the Church
Mission is not an optional activity for Christ’s disciples. If they are not gatherers, they are scatterers. Some supposed that a church may feature worship and nurture, leaving gathering as a minor role… Such a church is actively involved in scattering for the congregation that ignores mission will atrophy and soon find itself shattered by internal dissension. It will inevitably begin to lose its own young people, disillusioned by hearing the gospel trumpet sounded every Sunday for those who never march.
