Never seen the tongues signs and healing people follow the rules laid out in the Bible
I have.
One of the problems of mega ministry is that its focus drifts from the "lowliness, meekness, with longsuffering, forbearing one another in love, endeavoring to keep the unity of the spirit in the bond of peace", into self-aggrandizement and TV-ish production. But blaming that on the recrudescences of Pentecost and charismata would be like blaming gaudy, ostentatious, semi-truck-sized motor homes and automobile wrecks on gasoline.
Instead, I tend to blame it all on good, old-fashioned hubris and concupiscence.
Which is why I doubt most of it is from God.
