I don't know the 'Sword and the Switchblade' though the name sounds familiar - but I do remember having read 'Run, Baby Run' by Nicky Cruz. He probably mentioned Wilkerson, I can't remember the details of the book now having read so many over the years. I completely gave up reading any books of a religious nature a very long time ago because I'd overdosed on them, after a time they all ran into eachother and my head was buzzing. That's something I've stated many, many times on forums! Much prefer a novel.
Anyway I am not doubting what Sassy says, she tells the truth but, honestly, David Wilkerson's name and story did not ring any bells with me. There are countless stories of evangelistic preachers with tales of saving people from lives of sin, and healings, in print and on the internet & honestly I can't be bothered with them. Earlier on I said it all made me very sad and that I wasn't going to revisit the subject, I wish I had stuck to that but I will now. Nothing new for me to say in any case.
I need calm in my life and am quite happy with my relationship with God without the help of televangelists. Neither do I care if Sassy reads my posts or not, past caring frankly.
