This volume may serve to encourage a weary worker on the same field, or rouse some of Christ's unemployed to go and work in the vineyard. It may furnish a fresh illustration of the fact that the secret of power in Christian work is a close walk with God, and that self-sacrifice never fails of true success. It may be used by the Holy Spirit to guide some hapless wanderer into the way of life. God grant it may, and to Him be the glory' john maci'herson.
