We've touched on the importance of the missionary knowing the Word and of demonstrating the authority of the Word. This key deals with the practice of teaching the Bible as the central message and source of teaching and training in the missionary's ministry. References to the content and teaching of God's Word should naturally ooze out of the missionary from informal settings and conversations to formal meetings and teaching. God uses the Word to save and to transform lives. No other book has the same power, promise, and potential. Teach and preach the Word!
