The problem is that many church leaderships do not see the importance of extended prayer to prepare meetings for the moving of the Spirit of God. When leaders give themselves to hours of prayer and seeking God for Holy Spirit power to come into their services, we see the gifts of the Spirit being manifested, people on their knees weeping before God, souls being saved and healed, and others being freed from demons. The closest I came to it while watching Youtube were the videos of the Brownsville Revivial. I saw people weeping before God, kneeling before God, collapsing under the power of the Holy Spirit, the whole front of the church filled with souls turning to Christ. I never saw the dog-like barking or anything like that, although there have been reports of it. I tend to believe that it was demon manifestation as they were exposed and cast out. Derek Prince in his deliverance ministry encouraged people to cough demons out when they manifested. Perhaps that was what people heard in the Brownsville meetings. I saw people trembling under the power of God and it didn't seem to be put on in any way. Often when the glory of God is present, people tend to respond and react in unusual ways. But no leader was orchestrating it. The glory was coming from above, and not from the front. I just said these things as an example of what I witnessed in the meetings with the pastor who mentored me in the things of the Spirit.
It is significant that the pastor's defining work was J.C. Ryle's Holiness. He had a Methodist Holiness background, and was very strict on personal holiness, knowledge of the Word, and a foundation of personal prayer. One couldn't get away with even the smallest sin in his church. I once was invited to have dinner with a couple who went to a Oneness "Jesus Only" church, and the pastor told me in no uncertain terms that if I went and fellowshipped with those people, I would have to leave his church! That was how strict he was about purity of faith and doctrine. I respected him and stayed with his church.
But when I got married at the age of 25, I changed to my wife's church which was a more standard Charismatic church. It seemed to be okay for the first two or three years, but it got invaded by the Discipleship/Shepherding movement and the "covering" doctrine. Then I started to witness envy, jealousy, disunity in the eldership, pushing out of elders who dissented from the self-appointed "senior" elder's views, and gossiping. It was known that getting counselling from some elders was unreliable, because it was being gossiped around the church by the elder's wives! I ended up leaving that church in 1978, and have never associated with a Charismatic church since, but have been involved in a prophetic ministry with a leader (the son-in-law of my old pastor) whom I trusted.
I think that the Charismatic church that had the problems was not soaked in prayer and the seeking of God for His will. The problem arose when a dominant elder pushed his own will onto the church and this caused disunity and eventual division.
