Found this to be very helpful. It comes via Ed Stetzer’s blog:
A preacher of the Gospel – the greatest form of evangelism is simply preaching the Gospel.
Can be male or female – this gift is given to women as well as men. The first evangelists were women instructed to tell the good news to the Apostles that Christ had risen. The Samaritan woman in John 4 was the evangelist to an entire region.
Is a gatherer – that seeks the lost and gathers them to be a part of Christ’s church.
A builder – that lays the foundations of true discipleship. They should go beyond giving an invitation and having people pray a “sinner’s prayer” and make sure that Christ is fully preached and that the foundations of repentance and faith are laid.
An equipper – the Evangelist must mentor other Evangelists as well as train believers to make disciples.
A strategist – they can devise tools and strategies that attract the lost and enable believers to share the gospel more effectively.
A pioneer – they should lead the faithful beyond the church walls into the harvest field. They are able to see outreaches turn into new church plants.
