If Gloria Copeland and her wolf husband can affect hundreds of thousands of dumb sheep, leading them all to destruction, why shouldn't she be able to affect the weather. I'm just saying!
The most helpful for me has been learning to pray effectively, praying the Word, applying scriptures that deal with whatever the Lord put on me to deal with. There isn't a bit of power in praying something a congregation likes to hear, especially if a prayer is directed to the congregation. There's not much good in a memorized prayer, either. Folks pray the model prayer often as a standby, but few ever know any result from shallow prayers. The reason might be simply they are not regarding those words spiritually. At a Copeland meeting I experienced a 3 hour prayer session with Gloria leading it, teaching us how to pray the Word as we prayed, using that model prayer fully expanded to converse with Father God about issues of the moment.
It's amazing to me how some people find that sort of ministry to be evil. They got me praying like the Word says to do.
Maybe the problem is no prayer at all? Jesus spoke some powerful promises around prayer and speaking to objects with authority. So why not speak to a weather phenomenon? Why do some Christians limit what they can pray about? It isn't biblical to do that.
