The main cause of the spread of the gospel in the 1930s was the Great Depression. The economic hardship and suffering experienced by many people during this time led to a renewed interest in faith and religion, as people sought solace and hope in their spiritual beliefs. Churches and religious organizations saw increased attendance and interest in their teachings as people turned to religion for comfort and support during the difficult times of the 1930s. Additionally, the rise of radio and mass media during this time allowed for the gospel message to be spread more widely and reach a larger audience.
