Strang Report: When Fidel Castro came to power in 1959, there were 89 small Assemblies of God churches in Cuba which remained until 1989, then revival came. Since then the Assemblies have grown from 12,000 members to over 500,000.
Incredibly the government authorities agreed and encouraged them to continue their growth through a house church movement in order to accommodate everyone who wants to worship. Since then it has grown to include 3,000 house cell groups and over 900 Church buildings.
Not mentioned in the article–the AOG aren’t the only Christian groups that have been experiencing incredible growth in Cuba at the same time. There are also a number of indigenous Cuban church organizations that have grown in the same way—all of them experiencing healings, diverse gifts of the Spirit, miracles, and numerous signs and wonders in the process.
