No canvasser should exalt the book for which he is working above others that set forth the truth for this time. Should our canvassers drop all but one book, and concentrate their energies on that, the work would not be carried on according to God's plan. Minds are not constituted alike, and what might be food for one might fail to attract another; therefore, books should be in the field treating in a variety of ways the special subjects for this time. It will be necessary for the canvasser to make a wise selection. Let no one who is doing the work of God become narrow and short-sighted. The Lord has many instrumentalities through which He designs to work. When one book is exalted above another, there is danger that the very work best adapted to give light to the people will be crowded out. There is no need of contrasting different books, and judging as to which will do the most good. God has a place for all the voices and all the pens that He has inspired to utterance for Him. It will be difficult for some minds to fathom our most difficult works, and a simpler way of putting the truth will reach them more readily. Let the leading workers encourage the weaker ones, and show an equal interest in every one of the instrumentalities set in motion to prepare a people for the day of the Lord. Some would receive more benefit from papers and tracts than from books. Papers, tracts, and pamphlets that dwell upon Bible lessons, all need attention in the canvassing work, for they are as little wedges that open the way for larger works.—Manual for Canvassers, 47-49.
