These studies in the book of Malachi were delivered as addresses to the students at Mr. Moody's Bible School in Chicago, and then to my own congregation. They have also appeared in "The Record of Christian Work" in the United States, and in "Out and Out" in England. They are now sent out in a more permanent form, after careful revision, with the prayer that they may be used of God in calling His own children into the place of power without which form is nothing.
