The problem is, the theological aspect is not irrelevant in the way Thatcher's views on ice cream would be. Christ didn't come to teach people how to be good but that they couldn't be good apart from him. He called his disciples evil, and not because they were particularly unkind compared to other people, but because man is evil in the sight of the Lord, requiring a saviour. All of Christ's ministry was about establishing who he is and about redeeming man from the clutches of sin and bearing the wrath of God so that we wouldn't have to. It's the scandal of the gospel. Not just unmerited grace, but demerited grace. Not only not throwing somebody into hell as they deserve but bestowing such love on those who crucified him that they are drawn into the Kingdom of God as sons and daughters, having the incredible affections of God.
And people wonder why I love this God...
