This story begins at creation and finally only completes itself in the consummation when God is all in all. This is Paul’s gospel, and while it includes and encompasses the Plan of Salvation and leaves open how one might construct a Method of Persuasion, the gospel of Paul cannot be limited to or equated with the Plan of Salvation.— The King Jesus Gospel, page 61
A truncated gospel, the "atonement only" or "soterian" gospel just doesn't do justice to the love of God—and it doesn't transform people. We need a fully-formed gospel—the apostolic gospel, as Scot calls it—in order to see people transformed. Anything less is a mockery of what Christ did.
