Christian disciples are sent men and women — sent out in the same work of world evangelism to which the Lord was sent, and for which he gave His life. Evangelism is not an optional accessory to our life. It is the heartbeat of all that we are called to be and do. It is the commission of the church that gives meaning to all else that is undertaken in the name of Christ.
