Our purpose at IDS 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.
