Dear Mariel (and doves)

This question has been mulling around in my mind as I have a young gal (she is 23) living with my family right now who is in the process of divorcing her husband (he is 33 years older than she is. Her whole life has been a series of abusive relationships, from her parents who are mormon to siblings that sexually abused her to her parents insisting she marry this guy who was 54 when she was 19, just a really bizarre life).

Any way my question is this: does God really join unbelievers together in marriage?  I know it is a legal contract secularly speaking.  But my thoughts are that if two people do not acknowledge God would God assert himself in the relationship anyway?  I don't think so.

I am aware of Paul's admonishments to stay married if your unbelieving spouse is not rejecting you.  And I am aware that we are sometimes called to suffer undeservedly. The Pastor of our church believes that one should never get divorced.  This gal has only been saved for a couple of years and her husband is not likely a believer.  He has been to church a few times and is always uncomfortable - it is obvious that he can't wait to get out of there.  People can change, but they have to want to, God doesn't change people unless He is invited to change them. (which is were all the advice to women who want to improve thier marriages comes from in that they should pray that God would change themselves not thier spouses)

My apologies for the rambling nature of this post... mostly I am seeking advice and prayer I so feel the need to offer shelter and guidance to this girl, but would like to do so in a way that glorifies the Lord.

Your sister in Christ,
Jill
