These addresses on the Thessalonian Epistles consist of expository messages on these two letters, given over a period of ten weeks on the Lord’s Days at the Moody Memorial Church in Chicago. They were stenographically reported, but have been abbreviated somewhat by the elimination of considerable matter that was not deemed suitable for the general reader, and also because of repetition which can hardly be avoided in addressing changing audiences but would be needlessly redundant in a book. Even as it is, some things are repeated because of certain truths treated or alluded to in both Epistles. It is hoped that these will not mar the effectiveness of the attempt to elucidate the great lessons that St. Paul was used of God to present to this particular church.
