Welcome to the Grace Rock Video and Audio Library. Thanks for stopping by to see what is currently available from Dr. Oberholtzer. Listed below are a number of courses currently available. Some of the series are taught in an informal setting with some interactions with the class. Other studies are taught in a more formal setting with teaching first and then Q & A.  Gifts/contributions to the ministry are much appreciated.  Thank you!

Grace Rock Ministries believes in “grace giving” & “hilarious givers” (2 Cor. 8-9).


Book Studies


This is a verse by verse study of the New Testament book. Hebrews is constructed around a series of five major warnings to the readers. The book presents Jesus as Superior to all else in the cosmos. The Messiah Jesus is presented in all of His glory, majesty and superiority to religious systems. Practical applications are made throughout to encourage you to a life of holiness and deeper walk with the Lord.   (Dr. O did his Ph.D. dissertation on Hebrews Warnings)
