Would you say something or worry about fucking up someone's faith

I got invited to church by my coworker because I'm having open heart surgery next week. I've been getting all my ducks in a row especially with my kids in case I don't make it... Though my doctors are confident I'll be okay

I don't go to church. I'm a very spiritual person. I'm just. It religious. But she said she has seen with her own eyes her pastor cause miracles.

She said there was a blind girl up there and the pastor asked God to give her her vision back she could see. She showed me the girls Instagram. She posts about her journey with God and how God gave her back her eyesight. That she has been born blind and no doctor could do anything She has like over 10k followers.... I know that girl. And her family. She was never blind.... Would you keep that to yourself or say something. I didn't really say anything. Just kind of let that girl believe that....

@Grace. She's not my friend. She's my coworker. I just didn't know if telling her that girl was never blind. That miracle was faked would hurt her faith or something. IDK. I just know for a fact that girl was never blind and is just lying to people
