I've seen people discuss the concept of "soul mates" many times on the forum over the years, and I think that when I was younger, I used to believe in them.
However, something that someone posted a long time ago really made me rethink my stance: if God does makes one, just one, ultimate soulmate for you--what happens if, let's say, they make a wrong choice in their life (like drinking or texting while driving), and they are killed before you even have a chance to meet them?
Are you then doomed to spend the rest of your life alone, because that "one ultimate soulmate" God had for you is no longer living?
These kinds of questions make me lean towards more of a believe in workable compatibility rather than supposedly one true soul mate.
The older I get, the more I also think about how our culture defines marriage and a supposed soulmate rather as opposed to what God intended it to be. In today's world, a "soul mate" or even "marriage partner" means someone who makes us feel on top of the world 24/7, and if that feeling somehow ends, most people will move on.
But yet, God commanded His prophet, Hosea, to marry Gomer, a woman who was already known to be promiscuous, and ran to other men while she was married to Hosea--to the point where he would even have to go after her and retrieve her from these other men.
Did God specifically make Gomer to be Hosea's "soulmate"? If so, I'm pretty sure this is a soulmate that no one would want.
Whether or not God does make "soulmates", the purpose of marriage is still the same--to carry out God's will in our lives. In the case of Hosea and Gomer, His will was to give the people a real-live illustration of how God kept taking Israel back every time she ran to other gods.
And this, to be honest, sometimes makes me afraid to ask God what He truly wants my life to be.
