Are there excesses in the Charismatic movement? Are there ungodly people with selfish agendas in the Charismatic ranks? Yes... And yes again. The prosperity message has been corrupted, the healing message has been corrupted and the gifts of the Spirit message has been corrupted. Do we throw the baby out with the bathwater? No. But we definitely need to change the bathwater, the baby is starting to smell a little funny.
I was raised up in a Holiness church. I have been in the Pentecostal faith all my life. I was ordained in a non-denominational, charismatic church. I have seen, heard and been a part of the real work of God and what I'm seeing these days is disheartening to say the least. Anywhere there is the opportunity to be rich and/or famous, there will always be people ready to take advantage of that opportunity. Christianity is not immune.
The Bible teaches that God wants his people to prosper. The Preachers I hear these days seem to have a different definition of prosperity than God does. God wants us to have enough, with a little left over so that we can give to others. And that only comes when we are obedient and faithful. The Bible teaches us that God is our healer. God hears us when we cry out in our painful circumstances and He helps us in our times of need. But God has never promised us a painless, easy life with no hard times. Soft lives make soft Christians. We are told to persevere and endure as good soldiers; To count it all joy and learn to be thankful in whatever state we find ourselves. The Bible teaches that the Holy Spirit gifts believers "for the perfecting of the saints, for the work of the ministry, for the edifying of the body of Christ..." The gifts of the Spirit are not for personal gain or personal glory or personal anything else. They are for service to others and for glorifying God.
On the other side of the coin, there are those who are pointing out the faults with Charismatics and overlooking their own faults. Excess is wrong, but so is absence. Not teaching that God will provide for His people according to their earthly needs, teaching that healing is not for today and that miracles have passed away, and squashing legitimate spiritual gifts is just as bad.
