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!

Picture-Fulfillment: A Study in New Covenant Theology

“Excerpt 2 | What is a Covenant?

COVENANTS

What is a Covenant?

There is no debate that the concept of the covenant is a significant idea in Scripture (1 Corinthians 11:25, Hebrews 8, Galatians 4:21-31). But there is much debate concerning what is a covenant and how we are able to identify a covenant.
