so isn't that the calling of an evangelist?
In the Church the Holy Spirit gives out various gifts for the successful and proper spiritual functioning of the body of Christ.
Some to be pastors, some to be teachers, healings, faith, discernment, diverse tongues, interpretation, faith, etc, etc...
Evangelists have the gift of the gab. They just flow with the Spirit and talk Christ Jesus. Bob or Rita could witness to anybody
pretty well in any public situation. While we may all speak to another person about the gospel and share our testimony, most do
this intermittently now and then with people we get to meet.
But an evangelist is gifted to go boldly out into public places and proclaim the gospel and talk of these signs shall follow them that
believe to all and sundry.
The late great Bob Flannigan (who witnessed to me in a public shopping mall, and laid hands on me and prayed over me) was a master
gifted by God to say anything that could stop an unbeliever long enough to listen.
Bob would go up to people (in public) and say things like "One flash and your ash!" And then explain how Jesus could save them from
what was coming upon the world.
Rita walks up to people and simply asks them, "Do you Believe in God?" They respond, and she asks "Why not?" And away she goes...
The Holy Spirit gives evangelists in the Church a confidence and a zeal that the rest of us do not have in the same way. BUT there are nine
gifts of the Holy Spirit so we can all contribute to the growth and health and purpose of the body of Christ.
