I always enjoyed the preaching of the late Rev. David Wilkerson. This man knew how to preach sin and redemption.
Another thing I always liked about him was that when he was prophetic, he was spot on correct. Not like fools who try to pick dates, Rev. Wilkerson was given insights by God which have proven to be 100% correct.
Here is a You Tube video of his prophetic warning about the seeker friendly movement. While he preached this just as it was starting up, his warnings about it are all too true today.
We need more men and women like Rev. Wilkerson was. I know he has found his reward with the Lord.
