This account of the great commission in this text gets us thinking about evangelism. About this topic Martin Luther wrote: "The godly rejoice when the gospel is widely spread, many come to faith, and Christ's kingdom is increased in this way" (What Luther Says, p. 959).
The noblest and greatest work and the most important service we can perform for God on earth is bringing other people, and especially those entrusted to us, to the knowledge of God by the holy gospel (Ibid., p. 958).
