Some help please..

You don't know where she's going after death. Only God knows. Prayer is well and good, if it makes you feel better. Other than that, just be kind. Jesus dwelled with sinners and wasn't trying to make them repent, he just loved them, when all of society shunned them. That's the best you can do, is just love your friend, and treat her and her beliefs with respect.

Love and prayer, that's my suggestion.

I never understood this.

Yahweh is supposed to be merciful and all loving. Which means that he would look at a persons beliefs and go "ya know, they didn't believe in me, but they were a pretty good person. I'll let them into heaven."

So, either Yahweh isn't all loving and all merciful like is so often claimed, or your friend is no danger of not getting into heaven.

You can't really do anything but pray and show by example (not words) what Christianity is all about.

But just being honest here, if you knew that person was an atheist when you became friends, why would you expect them to act different later in the relationship. Vice versa that person should know that you are a Christian and believe in heaven and hell, and you don't plan on changing while you guys are friends.

I think most people think that they can change someone once they become close to them, but sometimes that is quite the opposite. You can't change people, people have to want to change themselves.

If she was an atheist before you met her and then you befriended her, that is like saying your ok with that part of her character (so to speak). I get my 3P's (Politics, Parenting, and Principles) out before I say I befriended someone, so that away there is already an understanding and less worry and confusion.

Respect her belief first of all. U wouldn't like it if she tried to challenge what u believed so just have respect and be the light God would want u to be.
