Sorry to put a dampner on his approach but I thought he gave these two mature aged ladies too much information that their is no way in the world could they take it all in .
As well as throwing in that God was identified by another name in the passages of the old Testament he quoted ?
I think it would have all gone well over their heads and they wouldn`t even remember a fraction of what he was on about let alone look anything up that he encouraged them to do.
Don`t get me wrong he did a marvellous job in his presentation it was just wasted on two old ladies counting time with no real Bible knowledge .
Just my 2 cents worth.
