I'm in the fence with praying for people in general. I'm agnostic and I hope fairly supportive of whatever people feel in religious terms provided it's not hate speech.
My gran believed in God and prayed for us and I felt it was a caring no strings act.
Then some years after her death I was working at a company with a Christian ethos (unrelated to religion I was there as a technical specialist so to speak) and what I saw there during prayers has very much made me view things with suspicion.
I once had to ban prayer meetings before group work (staff only and it was in the work day....obviously I couldn't and didn't ban praying but I had to end the in work time meet ups for this reason...and no it wasn't a religion that it was time specific need for prayer like islam) due to one of the vilest creatures I have ever met using her out loud prayer to belittle and bully other staff.
She was very well known in the local churches and considered a paragon of virtue (rather ironically even accepting she nicked her best friends husband who she was a carer for and behaved abomonably). However 5 minutes in her presence you quickly realised she was manipulative , borderline sociopathic and generally vile.
I did for a while consider it was just her until i sat in a board meeting for the same place and discovered a high level dorector doing the same thing during the premeeting prayer ....i was horrified.
Thankfully in the same place I met some truly truly amazing people who showed me true Christianity ( not for me personally but what it meant to others )
So if one of those people told me they were praying for me I would be highly highly offended (they didn't like me very much so wpuld probably pray I fell off a cliff to be fair ) but others I would take it as a nice thing
It's all about the intention from my view...it may well not be a "nice" thing but a passive aggressive dig. Only you can really say OP
