The launching point for the article is a discussion of a Christian dating website that claims they can find G-d's match for its users. It seems there are indeed a lot of Christians out there that put a lot of stock in hoping to find their soul mate, which can keep them optimistic, or mire them in holding out forever, or even lead to divorce when they "discover" that the person they married wasn't the soul mate they had once envisioned.
The debate among Christians is intriguing. Some are very adamant that soul mates exist, yet others refuse to think that there is one specific person out there for every individual.
I was a bit surprised to learn that Muslims don't believe in the notion whatsoever. Apparently, it places the "fault" of divorce in G-d's Hands if He is also the one who makes matches. After thinking about it a bit, it makes some sense, especially with the belief of multi-virgin reward in the great hereafter and continued practice of polygamy in many areas.
I'm not such a fan of Christian author Dannah Gresh's attempt to understand the Hebrew word "Yada" - which she elaborated on in a separate blog on eHarmony (yes, the lone comment is me).
The conclusion seems pretty moderate, and reflects some values that many Jews also hold onto. Namely, your soul mate/bashert is who you make out of your spouse. Certainly once married, it is appropriate to take this stance, and thereby put all of your mental and emotional energy into espousing that concept for the health of the relationship. Pining after a unknown, other soul mate can only get someone in trouble, as we have seen with former South Carolina Governor Mark Sanford.
