They haven't been called by God to understand it, and you're going to fix that.
I can't make God call anyone or understand. I can be God's servant and spread information about the gospel of the kingdom, the gospel of Christ and God's plan as revealed through scripture. What they do with the information is up to them. You've seen that there are various reactions to this presentation. I can lay out what I believe to be a clear and convincing case and yet if God doesn't open up someones understanding it will just be so much gibberish to them.
