If followers of Jesus don’t have a grasp of the Bible as a whole, what it’s telling and where it’s pointing, then trying to live as a Christian isn’t much better than being lost on a mystery journey caught in heavy fog without a light or compass. GPS: God's Plan for Salvation aims to give readers direction in finding their way around in the Bible, highlighting what shapes and holds it together. More importantly, it’s to help Christians live in line with God’s great purposes, in a way that truly honours him.
