While looking for an article that provides a theological foundation for evangelism and missions I found the following. I encourage you to skim or read the article entitled, “Reformed Evangelism,” by Morton Smith. Perhaps the best I’ve read. Helps Reformed thinkers apply Reformed methods to evangelism instead of merely whatever is currently popular at the time. I may use it as an outline for a Christian Education class in the near future. Smith taught at RTS and has served as Stated Clerk of the PCA (see more details below).
Morton H. Smith (born 1923) is a retired American Presbyterian minister. He was the first Stated Clerk of thePresbyterian Church in America, serving from 1973 to 1988, and also served as its Moderator in 2000.[1] Smith has degrees from the University of Michigan, Columbia Theological Seminary and the Free University of Amsterdam.[1] He taught at Belhaven College and Reformed Theological Seminary before becoming Stated Clerk of the General Assembly of the Presbyterian Church in America. Smith continues to serve as Professor of Systematic and Biblical Theology at Greenville Presbyterian Theological Seminary. (Wikipedia)
