"If you understand the nature of god of being invisible and untouchable and who scholars believe jesus was in the old testament ( the word of the lord or the angel of the lord), it's really not hard explain."
or
If you understand the the nature of a generation being long and multi-grouped and who JW scholars believe a generation was in the old testament (he and all his generation), it's really not hard to explain.
Could my point be made any clearer?
