Sounds like you made her group mailing list & a church's email list at that. I am sure she will not be upset by asking her to take you off the list.
I'm a Christian & I remember how I felt before I became a Christian. I would have told them to bug off if someone would have started shoving religion down my throat or would have laughed at them. Sometimes when people first become Christians they are a bit over zealous in spreading the Word. They just are excited over one of the greatest things to have happened to them & want you to have it to. Something like how we talk endlessly about Yorkies.
I work with a ministry & have conferences across the USA a few times a year that I attend. I always pray for the people I'm sitting next to on the plane that God gives me the perfect person to sit with for the next 5 hours. God never fails me. They notice a book I'm reading or I see they are reading & a conversation will start & we're talking about the Lord. I always wait to see if they are interested or ask questions & then we talk. But shoving down your throat - no way!
