Basically It sounds as if HIM is giving a speech on the history of Ithiopia in relation to Christianity. He also brought up good points on how the Christian community at one time rejected Ithiopia's version of Christianity. It seems as if he is recalling the great past of Ithiopia.

Then it seems as if the speech begins to turn into more history of people who chose to think themselves as gods, and lean to their own devices, such as those who built the tower of Babel. And then HIM sights that their endevorrs were destroyed.

I doubt Billy Ghrahm would invite a speaker who is telling people to run from Christ. If anything it sounds like HIM was affirming that InI should stay within Christ.

Atleast that is what I took from it.
