I have felt drawn to try to write what young Christians might easily apprehend, as a help to them to take up that position in which the Christian life must be a success. It is as if there is not one of the principal temptations and failures of the Christian life that is not met here. The nearness, the all-sufficiency, the faithfulness of the Lord Jesus, the naturalness, the fruitfulness of a life of faith, are so revealed, that it is as if one could with confidence say, Let the parable enter into the heart, and all will be right. May the blessed Lord give the blessing. May He teach us to study the mystery of the Vine in the spirit of worship, waiting for God's own teaching. Andrew Murray was a South African writer, teacher, and Christian pastor. Murray considered missions to be "the chief end of the church." He was one of the founders of the South African General Mission (SAGM) later becoming the Africa Evangelical Fellowship (AEF) in 1965.
