The Faith can spread across Africa like a flame.

When you go back to Africa, you must be active in confirming many more new believers, in establishing many more new centers, and many more Local Spiritual Assemblies. New believers re-vitalized the Faith; new centers broaden its basis; new Assemblies consolidate it. New believers bring new centers; new centers bring new Local Spiritual Assemblies; new Local Spiritual Assemblies bring new National Spiritual Assemblies; and new National Spiritual Assemblies bring new Temples! (He gave this last series of in a tone of rising enthusiasm and, when he said “bring new Temples”, he was smiling very broadly and triumphantly.) I want more believers, more centers, more Assemblies. Now is the time for the people of Africa to come into the Faith. Africa is like a dry field of grass. The Faith can spread across Africa like a flame.
