I have tried to compile in one article all the links to a definition that we’ve been discussing on EvangelismCoach.org
There are many definitions of evangelism.
Searching the web and my library for evangelism definitions, I find some are so wide to cover anything related to growing a church, some are so narrow as to the only three correct points in a scripted outline to a stranger, and some are in between.
It’s not my point here to list them all.
Here is the one I use:
Joyfully sharing the good news of the sovereign love of God, and calling people to repentance, to personal faith in Jesus Christ as Savior and Lord, to active membership in the church, and to obedient service in the world. (Definition adopted by the 202nd General Assembly of the PCUSA, 1990).
