1) The supreme goal of evangelism is to glorify God, not save souls.
2) The only power that can do this work is the Holy Spirit, not our own strength.
3) The one and only medium through which the Spirit works is the Scriptures; therefore, we “reason out of scriptures” like Paul did.
4) These preceding principles give us a true motivation for evangelism–a zeal for God.
5) There is a constant danger of heresy through false zeal and employment of unscriptural methods.
