The “Good News for All Nations” District Assemblies of 1968 were specially remarkable because of the release of the book The Truth That Leads to Eternal Life. This small, pocket-sized book turned out to be the most effective home Bible study instrument yet. A folder featuring this publication and containing a series of pointed questions was printed by the Society. That year brought a peak of more than 50,000 studies, an average pioneer enrollment of 3,881 (6 percent of all publishers) and an increase of publishers, the peak being 52,805.

The 1972 field service report showed a publisher peak of 65,693. Pioneers numbered 3,870, and 5,228 were baptized during the year.
