Welcome to In-Depth Studies!

IDS is a teaching ministry of Geoff Volker. Our purpose is to stimulate your thinking on significant Biblical issues. Our theological point of view is that of the Reformation in that we hold to the Doctrines of Grace (TULIP). We differ from Reformation theology in areas such as infant baptism and the Sabbath. We also teach from the perspective of New Covenant Theology. Take your time and browse our site – we hope we can be a useful resource for you!

The pages of our site are loaded with theological articles on a wide range of topics explaining our views. Be sure to visit the Reading Room while you’re here and feel free to download anything of interest to you. Don’t forget to visit Theological Inquiry as well. Theological Inquiry is the section of our site that provides you the opportunity to interact with us in asking any theological question that you’re facing.

Introducing Brad Woodlief as the Newest Member to the IDS Family

My name is Brad Woodlief.  I am married to my best friend, Michelle.  Together we have three children, Connor 8, Mallory Kate 7, and one in the womb.  Michelle and I both met Geoff Volker while we were on a mission trip in Minsk, Belarus, when we were students at East Carolina University.  We have benefited tremendously from his ministry and are excited to be partnering with him through IDS.


My passions are and continue to be evangelism and discipleship.  Even though I have read the Great Commission hundreds of times, every time I read Matthew 28:18-20 it motivates me to continue in ministry.  I do believe a part of the Great Commission is often over looked.  That is the part found in verse 28:20 that reads, “..teaching them to observe all that I have commanded you.”  It seems this aspect of the Great Commission is often left out after someone comes to Christ.  That is one of the reasons why I love the teaching and equipping ministry of IDS.  How we handle the Bible is important.  What we believe about Scripture is a direct correlation with how we live our lives.

My prayer is God will use me to help train and equip believers Biblically, so they can love and serve our God better.  This includes meeting someone one on one and teaching in group settings.  My scope of ministry includes college students, professors and young professionals.  It is my goal that after someone is grounded Biblically; they will then apply that knowledge and equip others with Biblical truth, thus multiplying themselves.  I have a unique advantage because I live in a college town.  Literally, over 30,000 students and professors come from all over the world.  Thus, God can use me to have a global impact for His Name and Glory.

To contact me, email me at Brad.Woodlief@gmail.com or find me on Skype at Brad.Woodlief. Visit Brad’s blog, after darkness, light shines.

IDS Hour – Book Review

The book “Total Church” is becoming the book of choice among calvinistic church planters. In light of this we at IDS have chosen to do a series of IDS Hours on it. “Total Church” is a British book that is authored by Tim Chester and Steve Timmis. The subtitle of the book is A Radical Reshaping around Gospel and Community. We hope that you enjoy the discussion between Geoff Volker and Paul Honeycutt on this significant book.
