Into the Wardrobe

Peter Kreeft quotes Soren Kierkegaard:

"I am terrified by everything, from the smallest gnat to the mystery of the incarnation."

Does anyone know where this extraordinary quote is from?

I found it! It is in this. A Baptism of Imagination: A Conversation with Peter Kreeft, By Ellen Haroutunian

Excellent, thank you.

He was a weird fellow.
