This companion book to Dawn of World Redemption (also 1951) takes the history of redemption from the first coming of Christ, through the age of the Church, to the world system of the antichrist, and then to the literal millennial kingdom of God on earth. The order of resurrections is given in detail followed by the teaching of the rapture and the Bema Seat of Christ. It’s hard to pin Sauer down on the time of the rapture in this volume but he emphasizes the “taking home of the church” and the rewarding of the saints at the Bema. It seems at times that Sauer includes Old Testament saints in the rapture.
(Erich Sauer was born in Berlin in 1898 to parents who were in the Open Brethren movement. His early dispensational plan and literal eschatology has made him a source for many modern conservative writers. He was the Director of the Bible School in Wiedenest, Germany, from 1937 to 1952. He died in 1959. This is one of his three major works.)
