Mennonite Mission Network has several short videos and video clips that can be used as moments in mission for your congregation. These videos focus on Latin America, South Africa, MMN ministries around the world, and other areas.
Also, consider inviting members of your church who have been involved with mission work, both locally and abroad, to share stories. There may be youth or young adults in your congregation who have taken a service trip or served for a year of more with programs like MVS and Service Adventure, or members of your church who volunteer with a local organization. The possibilities are endless!
