If I asked you, what's the most unnatural thing you can think of, what would be your answer?
Artificial intelligence, robots, androids?
Would the Incarnation even make your list? Because seriously, what could be more unnatural than divinity assuming human flesh?
The gospel is good news because it is unnatural. It defies the "natural" opposition of Creator and created, of God versus humanity. We are not doomed to forever relate to God as God's opposition. The unnatural act of reconciliation has taken place, initiated by a God who doesn't care about pretentious and ignorant human categories of the natural.
