The Laws of the Harvest

The Laws of the Harvest by John Lawrence was translated into Spanish in the past and widely used by Spanish speaking believers. It is now out of print, but missionary friends who have used it widely want to get it republished through some organization they know of. This according to Mrs. Lawrence. I haven't tried this but online used/new book sales may have copies since they do have the original in English. I have checked on the latter and some reasonable prices are available.
