wow man great testimony i relate to it so much, this same thing happened to me, i went through a week of torment, im not even joking this though literally popped up every 5 seconds I literally thought there was no hope, and I remember reading that scripture of the unforgivable sin and i can't explain it but I literally felt fear go through me, i was so scared because these thoughts kept coming but I finally confronted these thoughts the best thing to do is fight against the devil like jesus did by quoting scripture, every time i heard this though id just say praise the lord or jesus is lord and it would die down eventually i learn that jesus is infinitely forgiving and my torment has gone
