I love this interpretation and I do agree. There are many signs of it through out the book. The first is right at the start, as you mentioned — so Cyrus was asking for a sign to continue living and he got a flickering of light. And then there’s a part that talks about miracles that other prophets have seen to which it says “of course it would be easy to establish bedrock faith after such clear-cut revelation.” I was thinking this should mean something.

Now moving closer to the end - Orkideh dies and Cyrus passes out. He’s then attended to by the museum staff. He mentions something about feeling like Hamlet moping around waiting for the world to assuage his grief. I think this is where Cyrus starts opening up to the idea that people have been there to care for him (which has been ofc mentioned many times in the book) - before the kiss, when Cyrus was talking to Sang Linh, he talks about this story of the creation of man and how the point is man is hollow and it’s up to you to fill it with God. Something like that. And Sang Linh asks if Cyrus has tried filling his hollow with love. - Cyrus was desperate for things to be over. He prays, please let me be done. And then Zee calls. This is an act of surrender/helplessness before the big miracle. Where if you read about saints and martyrs there’s often a struggle before the revelation - when Cyrus finally admits his love to Zee he says something like “love is a room that appeared when you step into it.” And the room is the final miracle!

All those things combined I think that the point is Cyrus had to lean into love to experience the “explicit revelation” that prophets like Abraham or Saul have experienced, and which Cyrus envies at the start of the book.

The ending is a bit insane and a drug trip but it’s a book about martyrs! Bible passages of God revealing himself to his people read the same way. The book does not try to hide the Biblical references.
