Being passionate about obeying Christ’s command to make disciples of all nations is a good thing, and so is the willingness to go to hard-to-reach places to do it. However, good motives are not enough. As followers of Christ, we need to know the essential truths of our mission, or else we risk being ineffective or, even worse, misleading. In this series we’ll define ten terms that are indispensable to Christ’s mission: gospel, evangelism, conversion, disciple, disciple making, calling, missionary and missionary team, unreached, and church. We need a precise understanding of these terms if we are to be faithful witnesses in our own communities and among the nations.
