A recent expression of this challenge has been issued by Christian brethren from Australia. In their book, The Trellis and the Vine, the authors write, “The commission is not fundamentally about mission out there somewhere else in another country. It’s a commission that makes disciple-making the normal agenda and priority of every church and every Christian disciple.… Thus the goal of Christian ministry is quite simple, and in a sense measurable: are we making and nurturing genuine disciples of Christ?”2
