Raised as a OSAS Baptist, I was chagrined to learn that my favorite HS senior English teacher had been a Christian minister but was now "agnostic" and a year later (1968) in college when a friend became an atheist, so I asked my parents for a modern English Bible for Christmas and they gave me a NEB that was recently published, which I read through taking notes in the margins and repeated that study in the TEV, NIV and ASB Bibles through the years--thusly I learned from my own studies.
My church was not dogmatic about OSAS, and my dad was an engineer who when I asked him why he was a Christian said simply, "because it is the best belief"--hence the title of the first lesson on our website, which I created with the help of my son Paul in 2005. This is why I take a logical and scientific or systematic approach to interpreting Scripture, which I find the apostle Paul advocates.
Unless Bob Wilkin is my age, I think I probably learned what is on the video before he did, so I have not watched it yet.
Re RBT, yes I replied on CC with info learned from him three times recently regarding how God answers prayer, spiritual breathing and that the Greek precludes viewing Peter as the foundation of the church.
