So there are twelve guys in Israel with nothing but the sandals on their feet. They dispersed and did nothing short of change the world.
How did they do it? Evangelistic zeal. These guys really believed what they were selling.
St. Ignatius of Loyola was injured in the army and read a book about the saints and went out and changed the world. How? Evangelistic zeal.
So today, we have the internet, IPhones, Instagram, Facebook, Twitter, Tumblr and various other apps, devices, and instruments to help us spread the Word throughout the world. One might have expected that such a technological revolution in the Western world would have instigated a resurgence in the faith. But where is Catholicism growing? Places like Africa and China where access to technology is severely limited either due to economics or government censorship.
