Does God promise a mate for everyone?
Just for people who have a desire to marry (if you have the desire, He has a mate; if not, you have the gift of singleness).
Just for people He has favor upon.
No, not for everyone, but for some people.
No, not for anyone.
I don't think He promised, but I still act like He did.
I believe this because...
of a Scriptural basis (or lack therof).
it's what I've been taught.
it feels right.
it makes me/others feel better.
I don't know and don't comment on that kind of thing.
If you have Scripture references or another basis for your belief (or any additional thoughts on the topic at all), please feel free to share that in a comment.
Edit: Just realized it's going to drive me nuts if people choose the "Scriptural basis" option for one of the affirmative choices but don't share that basis. If you have truth, bring it! Edify!
