Volunteers spend a month in the summer vacation evangelizing in a target place. By using the action plan:
... a congregation is formed and turned over to a pioneer pastor who continues the work when the volunteers return home. A new church is planted, and one day this new church will plant another church! The church planting system is called "Summer of Service" (S.O.S.)

SOS DOORS. "Missions has given us concepts to inspire us - like Windows and Doors. But windows only allow us to view and stare at the size of the mission field. I like doors!
"Through the command of the Lord Jesus Christ, we can leave our doors, and knock on other people's doors, and share the gospel with them. Through the preaching of the gospel, they are evangelized, and churches can be formed out of these people who believe in the Lord Jesus Christ"
