My two cents worth....
Perhaps this is a good time to say that whenever the Warning occurs, placing ourselves completely in God's Hands and vowing to do whatever we can to use whatever talents He has blessed us with in His service and to honor and praise Him is all the matters. In a sense, worrying about whether this prediction stuff is right or not is trying to take hold of a steering wheel that only Our Lord has ever and will ever hold.
For example, if we do not worry about when and if, but place that in God's Hands and Will, this kind of anxiety and interaction will not occur. The important thing is the messages, not any messengers, dates or timetables. If Ron is correct, it will be because God allowed him to determine all of this and we should consider ourselves lucky and blessed to have been given the information ahead of time. Should he be wrong, it will merely be a reminder that, as a Broadway show title once proclaimed, all of our arms are too short to box with God. We should prepare spiritually, emotionally, morally etc, and place all in His Hands. Faith, patience, contrition and abandonment to His Will is all we should exhibit now.
