Kudos to you, Zero, for writing such interesting threads that really get us thinking!!!
I would first like to state that I have to disagree with Ugly's statement in an earlier post about marriage only being necessary if one cannot control sexual feelings. I know what Paul wrote, but I think that has to be balanced with God's original example of marriage in the first place (humanly speaking.)
I would guess that an idea of a "soul mate" would stem from Adam and Eve--here was Adam, all alone, and God "specially designed someone" "just for him", or so it appears. God didn't just say, "Ok Adam, I see you're having all these wild, out-of-control sexual urges that you just can't seem to tame, therefore, I am going to make a creature you can take them out on." (Now there's an interesting thought... did Adam even have any inkling of sexual feelings before Eve was created and presented to him?! Was sex and sexual feelings technically not created until Eve's appearance in the garden?) Likewise, God didn't create an entire harem of women and say, "All right, Adam!! Go for it!! Any one of these new-fangled critters could be the one. All you have to do is try them all out and choose one!"
No... that wasn't exactly God's attitude when He created the first marriage. It could just be my own observation, but I do think God intended much more for marriage than simply, "You can't control yourself so here's an outlet." After all, time and time again in the Old Testament, God refers to HIMSELFf as Israel's husband, saying things such as, "(when I took the people out of the land of Egypt (and they) broke My covenant, EVEN THOUGH I HAD MARRIED THEM." (Jeremiah 31:32) If God truly thought that singleness was the ultimate state of being, I personally don't feel that He would have referred to Himself as married. (This doesn't meant that singleness is the highest calling either, what I believe it means is that there are different callings for each of us.) I personally always believed that the main point of Paul's writings was, "If God calls you to be single, be single. If God calls you to marry, then marry. Whatever He calls you to do, do it all to His glory and to the best of your ability, in either situation."
Keep in mind as well that THE CHURCH is referred to as THE BRIDE OF CHRIST. Once again, I don't see God saying, "Son, I know you don't sin but I also know you're having some struggles holding back certain feelings, therefore, we are going to create a bride for you as an emergency outlet..." No, I think God had much bigger intentions for marriage than supposed primal and carnal urges. And I know that these are rough examples... it's not accurate to speak of the marriage of God vs. an earthly marriage, I know, but all things on earth are patterned after Godly things that God originally established.
I really respect the thoughts here that believing in "several" candidates might lead to a thought of, "Oh, well at least I have several backup plans out there if need be," but, living in a fallen world, if we believe in only one "soulmate", what happens if: that person dies in childhood or before we meet them? What if they decide to marry someone else? (A soulmate will have just as much free will as we do.) What happens if we do find and marry that person but they pass away or leave for someone else? Abraham is best known for his life with Sarah, but after Sarah died, few people ever seem to remember that Abraham took another wife (I believe her name was Keturah... sorry... don't have time to look it up right now) and had at least five other children that were named, if I remember correctly (feel free to correct me if I'm wrong.)
Maybe it's different for each person, I don't know. In the Bible, when one person passed on, God was prepared to anoint someone else. I don't know if He does this with marriages as well.
I have heard it said that the reason many Christians are not married is most likely because 1. the person God is asking to marry us doesn't want to obey, and/or 2. we ourselves refuse to obey and marry the person God wants us to marry as well. If one person is willing to obey the Lord and the other is not, we have free will. I don't believe God forces people to marry each other. So maybe, God will say to the one who is willing to be obedient, "I've chosen someone else for you." I can't claim to know...
Maybe for some, God does create THE ONE and for others, it's like a "choose your own adventure" story, I don't know. I suppose it boils down to what we're always told to believe, that no matter what, we have to seek God out for His ultimate plans for our lives, step-by-step, whether that includes a significant other or not.
