All of a sudden came across this math quiz on Facebook and I just had to prove it geometrically, Sum of natural numbers = sqrt of sum of natural cubes (Nicomachus's Theorem: first proved by the ancient Greek mathematician Nicomachus of Gerasa around 100 CE):


There's a whole history of this. But basically standard geometric proof is this:

How does the Right demonize the others? By saying things like "But I think what that really comes down to is that these cartels have zero value for human life" @46:59 in this interview by Allie Beth Stuckey with her brother Justin Simmons. It's a failure in understanding total depravity (by redefining it as absolute/utter depravity):

Received my modern guitar from this Chinese (Guangzhou) instrument manufacturing company called Donner which has gained popularity. This is a Donner Hush-I Guitar. Ordered from TEMU, but it's shipped from Bordentown, NJ which took only about 2 days. First test seems great: Sound quality, look and feel. Specifically, the action. Action distance had been a horrible experience for me for my previous guitars.

Speaking to Wayne and Tina, and Carol made me realize that Crossroads may actually have an unhealthy split of faith and work. That if you want theology, you've got to go to a special program; ordinary church life is just for the non-theological members because pastors' sermons are enough. Some of them appear to have this idea that you become member so that you get taken care of by an elder. This is such an inverse of the truth: The elder cares for all who are welcomed until they love becoming members.
I also notice that American Christians to love to chat about non-personal matters, like how Feeding Hands work; rather than anything related to them personally. So basically, anything you can get from ChatGPT A.I. I have to redirect them back to something personal, subtly.
Pastor David Lee's sermon on 1 Samuel 3:1-21 made him bring up how he has this guy friend whom he chats with daily even more than his own wife so to speak until his friend didn't pick up his call which relates to verse 3 when God's words were rare - God's silence. It's interesting correlation, but I would pursue that verse more inquisitively, that "rare", "not many", do not mean total silence.
