Evangelism is sharing the good news of Jesus Christ (i.e. the gospel). As with all other aspects of Christian ministry, evangelism should be done in the power and under the direction of the Holy Spirit. Because evangelism is an expression of God's love for those who don't have a relationship with him we have to trust him to bring about the results we seek. At Life Church Ministries, we do evangelism in two ways: proclamation evangelism and relationship evangelism.
Proclamation evangelism is done through evangelists. New Testament evangelists are a men and women anointed by God to proclaim the gospel to broad audiences that often don't know them personally. In other words, they are anointed to win strangers to Jesus Christ. Put them on a street corner, at a bus terminal, a train station, or an airport and they will successfully win people. Unlike the most of the people who operate with the title "evangelist" in traditional church settings, a New Testament evangelist does his/her best work outside the walls of the church.
This is the form of evangelism that is most appropriate for the rest of us. God wants us to develop authentic relationships with the people we come into contact with from day to day: coworkers, classmates, neighbors, etc.
