From my experience of the Cuntstian I had to share breathing space in an office for two years it is done for their benefit and not yours.
She would randomly thrust her prayers on poor unfortunates - disabled people, poor people, women taken in sin me in order to rack up points with God.
Her version of Christianity was unremittingly judgmental and joyless.
However, there was also someone in the company who went on to become a Baptist pastor.
He was sincere in his faith but entirely tactful about the help he could give - both spiritual and practical. He'd never force it on anyone but you could see where his code came from.
He was also filled with the Wrath of God at the absolute worst of a long line of her hurtful judgments. I will always remember that.
To be brief: GodSquad (for that was the kindest name we called her) told a secular Jew whose non-Jewish stepfather had cancer, that she would pray for him, but to give him the best chance my friend and her mum should convert 
.
I don't know how my friend kept her hands off GodSquad. I think she was too shocked.
Do you know what? He died. Must have been God's plan.
Chris - the future pastor - heard about this. He told GodSquad exactly how disgusting he thought she was in front of us all. He was furious and filled with righteous rage. He was probably the only person she couldn't dismiss as Godless.
The moral is: other Christians are available and they can be a lot of fun
