I’m sorry that all this has happened. Pride does go before a fall, but when my 11 yo daughter was dying to read the Twilight series, it was Marc Driscoll’s informative and humorous YouTube video on the subject that convinced her that Twilight wasn’t something she wanted to put into her brain.
I have similar experience. I was saved 37 years ago at a Bill Gothard seminar, even though later he was found to be straying significantly from the mark. And Peter denied Jesus and later sided with the Judaizers. We must beware, not merely of others, but also of ourselves!
