CareerTrends describes evangelism ministry as a nonprofit with a "chief aim is to win converts to Christ. Different Christian denominations go about evangelism ministry in very different ways. A minister who is involved primarily in evangelistic ministry is called an evangelist. In addition to vocational evangelists, many churches encourage their lay-people to become involved in evangelistic ministry by sharing their faith with others."
