You ask about the pamphlets published under the general title of Redemption. These were published between the years 1874 and 1878. The main parts were embodied in "The Spirit of Prophecy" Vols. 2 and 3, published in 1877 and 78 and this material also formed part of the basis for "The Desire of Ages" published in 1898. There are some things in these pamphlets which are not found in "The Desire of Ages", however, for the treatment of some phases is much broader in these early pamphlets than could be possible in presenting the life and ministry of Christ in one volume.
