Interesting list of preachers who have made an impact of the past generation.

Missing from the list would be the Pentecostal/ Full Gospel preachers that have been used significantly to advance the gospel. There is a great danger that a generation may come that knows nothing of the expression of charismatic worship and accessing the power available through the “promise of the Father.” No doubt culture resistance to “undignified faith” plays a large role in this reality.
