A fairly interesting talk - he also gave it or a similar one for Bethel graduation talks.

A few things that stuck out to me:
He begins by saying that we have to be careful when imitating humans as they are imperfect - but we can imitate EVERYTHING about angels as they are perfect. (And what about the angels that became demons? What about the angel that became Satan? What about the angels that had sex with earthly women?) He does address the angels that had sex later on, but its totaly contradictory.
He has a large part going on about how humble the angels are - then immediately following this he goes into great detail about how they are like "super hero's".
