I know there was another thread about the AoG and many are truly in love with God but there are so many AoG churches (all independently “governed” by whoever is the pastor with no centralized authority – similar to Baptists) and many of them promise great miracles as part of the package deal of faith. Remember, they are a “pentecostal” group after all. Some don’t believe you are Christian unless you speak in tongues!
But again, these are overgeneralizations because the internal diversity within the AoG is so great.
As for this commercial (I live in Brazil so I haven’t seen them or even heard about them), well, I think it is a little daring to “promise” miracles (as many AoG do in fact – especially in Brazil where they are the second largest denomination after Baptists) but Jesus healed several blind people, Paul had the scales drop from his eyes when he went to see Ananias and I think blindness is an analogy for walking without Christ anyway. So I see the aim of the commercial more at showing the world how to come out of one’s spiritual blindness (à la “Amazing Grace” – “… was blind, but now I see.”)
