The act of sharing the Good News of Jesus Christ is called evangelism. Evangelism is the responsibility of the whole church for the whole world. The Good News is not something we come to church to hear; it is something we go from church to tell.
At the end of Jesus' life on earth, he gave this charge to his followers: 'All authority in heaven and on earth has been given to me. Therefore go and make disciples of all nations, baptising them in the name of the Father and of the Son and of the Holy Spirit' (Matthew 28:18-19).
