The Gospel is "good news" and we do have a savior, but if that's all he believes it is, then that's a very shallow understanding and leaves out several crucial steps.
You mean there's a resaon God gave us the Ten Commandments before He gave us the cross?
You mean there's a reason Paul spends three chapters explaining to us our sin (Rom. 1-3) before teaching about grace and salvation (Rom. 4-5)?
