I wasted the time on this video...The guys is extremely short on bible and very long on the human philosophy of Lewis and himself...Matter of fact, this guy never once mentioned a bible verse that I can remember...And that's really easy to understand why...

You obviously did not access the links to Dr. Jerry Walls contained in my post #70. Dr. Jerry Walls uses many biblical references in those video clips. (Go see for yourself.) He was not preaching a sermon in the clip you watched in my post #78, but was just giving a talk about C. S. Lewis, and that is why he was not quoting the Bible left and right, like he does in some of his other work.
