All evangelism is important but all evangelism is not equal. There is a difference between a church having an evangelistic invitation (e.g., altar call) during a worship gathering and a church sending members to share the gospel with unreached people groups. Yet, most people would say both of these churches are evangelistic.
(Food for thought: While gospel proclamation occurred when the first century churches gathered (1 Cor 14:24-25), most of the evangelistic activities in the New Testament occurred in the highways and hedges of the communities.)
All evangelism is important but all evangelism is not equal. There is a difference between a church teaching members to be evangelistic in their offices, schools, and neighborhoods (generally, meaning reaching people of the same cultural identities as themselves) and a church teaching members to share the gospel with the 1st generation Yemeni living across town.
