Both the Methodist Church in Britain and Discipleship Ministries of The United Methodist Church have come out with videos recently about evangelism.
The video from the Methodist Church in Britain, entitled "Stepping Out in Evangelism and Growth" is a nice, 8-minute long introduction to the MCB's approach to evangelism and the importance of evangelism in the life of the church. It comes out of a recent MCB focus on evangelism and growth.
The video series from Discipleship Ministries is part of their See All the People campaign. While there is a series of 19 videos (and counting), the two videos "What is 'See All the People'?" and
"#SEEALLTHEPEOPLE" provide the best overview of the approach to evangelism embodied in this initiative.
