The entire universe is based on vibrational frequency. I believe any type of mental concentration is sending out vibrations some call it meditation, some prayer some call it king about you. All are positive and good. If someone tells me they are praying for me I always say thank you as I truly believe good vibrations are always positive.

Send her many atheists forwards....

Respond with witty texts like "Man is the measure in all things." Protagoras;
"I will not be pushed, filed, indexed, briefed, debriefed, or numbered! My life is my own." Patrick McGoohan;
"Even traveling at the speed of light, an ascending Jesus would still be in this galaxy." Joseph Campbell.

This one scream all over the place that you need new friends....

Yes I know I my middle child does it all.the time! I always overlook it! But I think actually think it is rude. wish u well.

Not seeing the texts themselves (I am, not asking to see them), I can't really say what her intent might be... other than agreeing with other comments that say she doesn't respect you in the same way that she expects others to respect her.

There was a comedian, I forget who, sho said that behind every "bless your heart" is a little "fuck you!", and I kind of agree with that.

If it were me, and I am glad it isn't, I'd think up snaky replies.
"Jesus loves me?",
Then why doesn't he ever text me himself?
I took out a restraining order, so tell Jesus to leave me alone.
He can't even cut my lawn right.
Funny, he's never even sent me a card on my birthday...

In the end she needs to understand that if she wants you to respect her beliefs, then she needs to respect your non-beliefs.

I have a couple friends who do the same. They know I don't believe in sky pixies but they send me that stuff anyway. It might be best to respond by telling them how special they are, then leave it at that.

If I had a friend who suddenly started texting me with god stuff I'd be worried about their sanity but all you can do is ignore it, it's all meaningless if well intended (I hope) If your friend really cares then cool, if there's a god component to that care I would suggest that you're not leaving anything behind that you need if you put a bit of distance between yourselves.
