Evangelism is the Christian practice of proselytization. The intention of most evangelism is to effect eternal salvation to those who do not follow the Christian God; others believe it is to inform others about the Kingdom of God. Evangelism is done in obedience to the Great Commission, a command from Jesus to his disciples to proselytize, as recorded in the New Testament. Christians who specialize in evangelism are known as evangelists, whether in their home communities or as missionaries. Some Christian traditions consider evangelists to be in a leadership position, and they may be found preaching to large meetings, and in governance roles. Christian groups who actively encourage evangelism are sometimes known as evangelistic or evangelist.
The communication of Christian faith to new geographical areas and cultures is often referred to as evangelization, or specifically, world evangelization.
