There is a Midrash that asks what Hashem is busy with in Heaven. The answer is that he is busy with matchmaking, as that is something very difficult to do.
There are three references to this idea, from the Torah, the Prohets, and from Scriptures. The first reference comes from Lavan and Betuel, Rivka’s brother and father. They use the words, מה׳ יצא הדבר, that this matter, meaning this match between Rivka and Yitzchak is from G-d.
The second example comes from the Book of Judges and the story of Samson. He becomes fixated with a Philistine woman. His parents were upset, but were not aware that מה׳ יצא הדבר, that this was part of a Divine plan.
And the third source is from Mishlei, known as the Book of Proverbs. In Chapter 19 verse 14 it says, מה׳ אשה משכלת, “an intelligent woman comes from Hashem.” This is also a matchmaking Pasuk. It is saying that if one is blessed with an intelligent and G-d fearing wife, it is a gift from Above.
Matchmaking seems to be even more difficult nowadays. Perhaps if people would pray more to G-d, asking for the proper mate, he might just answer. After all, He is the one making matches, anyway.
