Ok, so this is Joel Osteen. This is a ritual he and many other Word Faith teachers have at the beginning of their meetings. What you need to grasp is that the undergirding belief is that Speaking words gives them power to change physical reality. Thinking isn't quite enough, you have to say it out loud. By doing so, and not wavering on saying it, eventually, what you are saying will be real.
The idea is that we are in 'god's image' and as god created the world by speaking it into existence, so we have that power too.
I've seen a few of them follow their logic in a circle that says that if god said black was white, it would be true, because whatever god says happens.
So they will pore over the bible, find a verse that seems to align with what they want, and say it out loud as a personal affirmation/incantation and believe strongly, and it will come to pass.
Obviously, the genesis of the pomo philosophy and this sort of fringe religious nuttery are very different, but when you look at how the two perspectives operate, wrt being convinced that material reality isn't fixed and is malleable with the use of words, where everything is predicated solely on self-belief, I think it's quite obvious that we are talking about a metaphysical belief system, which is why I talk about Genderism as a neo-religion. In practice, it is simply indistinguishable from religious practices.
It masquerades as a human rights campaign, but that is just part of the proselytism.
