"This is crucial for our peace, because we shape our God, and then our God shapes us" (pg. 182).
We "shape our God"?
What is odd is that he does both Schleiermacher (see the chapter entitled "Rocks everywhere") and now Feuerbach without any irony. Just like he did Erasmus in the first few chapters-right down to the lack of clarity in Scripture!
What's actually most annoying about the line is that it presupposes what we need is a better "concept" of God. A better "concept" of God can actually be nothing more than a new law for us to obey and correspond to.
What we actually need is God himself, present in Word and sacrament justifying and sanctifying us! This isn't a better concept of God, it's God himself doing God to us!
There is actually much unintentional hilarity when he describes what is pretty much Luther's concept of the hidden God and says "wow, if that God was real, then that would destroy us." Yes, you got it! It does!
