Bishop Michael Nazir Ali asserts that churches are called to engage in mission from everywhere to everywhere. By that I take him to mean that mission is to be at the heart of church life, that all Christians are called to be witnesses to Jesus in the words we speak and the lives we live wherever we live. But more than that, churches are called to have an involvement in both local mission and global mission.
In my experience if churches engage in mission at all they are locally focused and tend to leave the global to the enthusiastic few. However, as congregations recognise the primacy of their global nature and calling they will be far more effective in their local mission and outreach. As Bishop Lesslie Newbigin wrote in his 1994 book The Open Secret, “Mission is the proclaiming of God's kingship over all human history and over the whole cosmos. Mission is concerned with nothing less than all that God has begun to do in the creation of the world and of humankind. Its concern is not sectional but total and universal.'
