Very well said.
I do believe though, that some folks get overly inflated with what God HAS shown them; get overly confident in their own astuteness or spiritual stature
and get sloppy in their wording. There is usually a valid Biblical trough underneath somewhere. But their sloppy wording gives the enemy plenty of room to scream.
You can have 10 people in the same Bible class and end up with 10 different interpretations of what was taught.
That is nothing new .. and it's because we are humans and we can miss it. But .. one of the secrets is knowing you're just human and you can miss it - and therefore the problem comes from "believing your own press" - instead of relying on the Holy Ghost to teach you the truth of what you heard.
