Ron Wallace shows that the 144,000 Jewish servants of God in Revelation 7 will have a ministry of evangelism. However, for a variety of reasons, some believers think that this will not be the case.  They reject the term "evangelist" as applied to these servants.

But Ron will show that the only significant function of a servant of God is to proclaim the gospel, expecially in the time period after the rapture of the Church.
