Without the Bible, world evangelization would not only impossible but actually inconceivable. It is the Bible that lays upon us the responsibility to evangelize the world, gives us a gospel to proclaim, tells us how to proclaim it and promises us that it is God’s power for salvation to every believer.
It is, moreover, an observable fact of history, both past and contemporary, that the degree of the Church’s commitment to world evangelization is commensurate with the degree of its conviction about the authority of the Bible. Whenever Christians lose their confidence in the Bible, they also lose their zeal for evangelism. Conversely, whenever they are convinced about the Bible, then they are determined about evangelism.
