And I said yes, so go to the info section for this video if you're interested in that. And you will find hours of me talking about Tim Keller's views, theology, critiquing them, the ones that are problematic and not biblical or not orthodox or unwise, and there's quite a few of those, that's why a book like this was written, and it's why I thought that it was necessary for me to do this, because I just didn't think that there were great critiques out there, there's some, but not very comprehensive, and so I wanted to give a comprehensive critique, and hopefully that's what I've done, hopefully that's what I've brought to you, this particular book Engaging with Keller is out of print, if you can find one, it's a great book, it doesn't cover everything, because it was written I think in part in 2014, but it covers some of the major issues, they haven't changed, and probably the shortest chapter, and if it's not the shortest, maybe the one that would, when I whittle it down into the bare components, become the shortest, becomes the shortest, is the chapter we're going to do today, which is the last chapter in this book, in Engaging with Keller, and it is all about Tim Keller's ecclesiology.
