Finding your "soul mate".
There are currently approximately 8.3 billion people on the planet. The idea that there is one person to whom you are perfectly matched and that it is God's will that you seek out and find that person and marry them is pretty preposterous. And if it is true that there is "one person" that it is God's will that you find and marry, well, then having been married twice I am forever out of God's will because I obviously missed it.
The concept of "soul mate" is not a Christian concept. It comes from Platonic gnosticism. To Plato, souls pre-existed in the ether and were mated to one another in the ether. Then when a body was ready the souls were poured into the body. Then it was your mission in life to find the soul that you were mated with in the ether, your soul mate, and finding your soul mate would result in perfect harmonious bliss.
By contrast, the Judeo-Christian belief is not that we have souls but that we are souls... that everything that we are, body, mind, spirit is created in the womb and nothing pre-exists prior to that creation and that these are inseparable except by death when the spirit leaves the body. And what I mean by "we are souls", the term for "soul" that is used in the OT, nephesh, means "living, breathing creature." It is also used of animals. Animals are nephesh, living breathing creatures. They do not have souls, they are souls (Genesis 1:21 So God created the great sea creatures (nephesh) and every living creature (nephesh) that moves, with which the waters swarm, according to their kinds, and every winged bird according to its kind. And God saw that it was good).
I'm not on any dating sites any more and haven't been in a good while, but nearly every woman's profile, especially Christian women, says she's looking for her "soul mate". It ought to say "next soul mate" because her last one was her soul mate, at least until he wasn't anymore. This idea that your life is supposed to be perfect harmonious bliss is pretty destructive. It doesn't exist in nature. Life can be good, and it should be. But perfect harmonious bliss? That's why people keep going from one to another.
So, what is "God's will" for finding a mate? That we choose wisely. Which obviously, I haven't.
