I'm not quite sure how to put this but God is love but He is also a God of wrath. He is forgiving and gracious but He does not tolerate outright sin. I think you should pray and "plant the seed" just once if she's not a Christian. Do minister to her if she is because iron sharpens iron. She, whether she's been a Christian for 2 days or 2 years, deserves to be sharpened by her fellow believers. Be do refrain from blasting her
in the flesh. I believe it is better for someone to deny Christ wholeheartedly than follow Him blindly. He didnt call us to be blind sheep; He called us to test all things with His Word. Do show them the word and do minister. Just dont flesh out.
And about the things you think are wrong, show them both sides of the story. Again, dont blast "You're going to hell!!" at them cause that would even scare me! Show them that you believe God has shown you it is wrong and let her decide.
Just my two-cents

Edit: Oh dear I forgot what I really wanted to say

Courageous is a wonderful movie! Thanks to all that recommended it
