You make an excellent point.
The chances of him being real, visiting GLP, posting the truth, AND people believing him are very slim to none. The Age of Aquarius is about using your mind.

The lesson is. Don't be afraid to let your imagination run wild every once in a wild. Think the impossible. Do you think people in Jesus's day would imagine airplanes today. Probably not, but somebody had to think of it throughout time. Don't limit yourself and allow yourself to think outside the box.

I try not to focus on the Messiah/Jesus/Nobody meme. Thinking of that implies that we are not all equal. And then greed for a higher status incurs. That just opens the door for evil.

Think of Abraham/Moses/Jesus/Nobody? as just a man God uses to accomplish his means. The Glory is Gods, not the prominent figure of the Age.
