ya might point out what the Bible says about being unequally yoked. Ya might point out how muslims treat women.
I would say something if it were a friend of mine. The trick is saying it in a loving manner and not getting sucked in to a major argument.
.Either way you will probably lose her as a friend.
Here is the verse which covers many associations, not just marriage. But it especially applies there:
"Be ye not unequally yoked together with unbelievers: for what fellowship hath righteousness with unrighteousness? and what communion hath light with darkness? And what concord hath Christ with Belial? or what part hath he that believeth with an infidel?" (2 Corinthians 6:14,15)
The Muslim is the infidel. True.
Unequally yoked???
She's going to be scrambled eggs.
I dated TOO MANY non-christian women in my past. Thank GOD I never married any of them.
Now, I won't even think about asking them out unless I know they are. Missionary dating is the worst kind of dating.
Its BAD ENOUGH dating somebody who's not a christian, I CAN'T imagine dating somebody whose religion openly opposes mine.
Personally, I'd see this as she's choosing a possible husband over her God. She's willing to not only take a husband but accept his religion, which means denying hers.
This is the case when accepting ANY religion over christianity. But more so with Islam, as one must not only renounce Christ for Mohammad and Allah, but true Islam is violently opposed to christianity.
If she thinks she can enter into a relationship with him and still retain her "christianity", he WILL BE violently opposed to her.
