神のおぼしめし	1369	


God is example #1 in the daijs definition:
https://kotobank.jp/word/思し召し-454324
１ 相手を敬って、その考えや気持ちをいう語。お考え。ご意向。「神の思し召しにかなう」「せっかくの思し召しですが」

I have encountered twice now in the God context, with people trying to understand tragic events. ("Is this just God's will?")

"The will of God" use is fully 50% of uses of this term. We even have an entry for 神の〜.  I think "will" should be in the glosses for people who don't think to do a phrasal lookup from 神.  Since it's 50% of uses, I think it should be an early gloss.
