In Christianity, evangelism or witnessing is the act of preaching the gospel with the intention of sharing the message and teachings of Jesus Christ.
Christians who specialize in evangelism are often known as evangelists, whether they are in their home communities or living as missionaries in the field, although some Christian traditions refer to such people as missionaries in either case. Some Christian traditions consider evangelists to be in a leadership position; they may be found preaching to large meetings or in governance roles. In addition, Christian groups who encourage evangelism are sometimes known as evangelistic or evangelist.
The gospel
The word evangelist comes from the Koine Greek word εὐανγέλιον (transliterated as euangelion) via Latinised evangelium as used in the canonical titles of the Four Gospels, authored by (or attributed to) Matthew, Mark, Luke, and John (also known as the Four Evangelists). The Greek word εὐαγγέλιον originally meant a reward given to the messenger for good news (εὔ = "good", ἀνγέλλω = "I bring a message"; the word "angel" comes from the same root) and later "good news" itself.
The verb form of euangelion, (translated as "evangelism"), occurs rarely in older Greek literature outside the New Testament, making its meaning more difficult to ascertain. Parallel texts of the Gospels of Luke and Mark reveal a synonymous relationship between the verb euangelizo (εὑαγγελίζω) and a Greek verb kerusso (κηρύσσω), which means "to proclaim".
Approaches to evangelism
Evangelism can include preaching or distributing bibles, tracts, newspapers and/or magazines, by the media, street evangelists, etc. The Bible records that Jesus sent out his disciples to evangelize by visiting peoples homes in pairs of two believers (cf. ). In the same text, Jesus mentioned that few people were willing to evangelize, despite there being many people who would be receptive to his Gospel message.
The child evangelism movement is a Christian evangelism movement that originated in the 20th century.
