Tom Wells writes with the conviction that when it comes to cross-cultural mission, Christians must cmoe back to first principles. Humand need and world conditions are not the starting point. The gospel is a call to know and worship God, and the primary conviction of the messenger must begin with the vision of God. Only then can the church truly respond to the command to 'declare his glory among the nations.' This is a challenging book, and equally relevant to Christians at home and abroad. It treats missionary endeavour not as a separate interest but as basic to Christianity itself. By reference to David Brainerd, William Carey and Henry Martyn the author also shows the true inspiration which lay behind the missionary movement of the eighteenth and nineteenth centuries.
