Edit: I do see some that use 3rpm so those would always be backwards at 30 seconds. 50hz supply would also change the rotation speed. My turntable is very predictable at least, so i guess I'll take the personal win and go.
That's actually more of a doctrine that is made up by the organization and less something explicitly stated in the book. There probably are some psalms or other references that use the word (translated as) "unchanging", but in context, the original audience would probably not have interpreted it in the same way. Think God's love and power will never fail, not God will literally never experience anything or change. In the 10 commandments story, Moses has a conversation with god and changes his mind.
Still issue? Idk 😂
