Evangelism, A Concise History by John Mark Terry and published by Broadman & Holman.
John Mark Terry weaves a fascinating account of the human means that God has used to communicate the Good News from generation to generation. The book begins with Jesus and the Apostles and then continues with the Church Fathers, revivalists, scholars, pietists, reformers, personal witnesses, mass evangelists and media evangelists; all so different yet bound together by a passion to communicate the grace of God they've experienced in Christ. With one voice they, like the apostles, say "We cannot keep from speaking about what we have seen and heard."
