I think it's more that Lois & Clark are "destined", "soulmates", "fated", whatever/however you wish to put it, to be together, and that, shall we say "beings" or in this case a "being" of a higher nature (god, angel, hyper-developed alien, whatever) took steps to ensure that they would finally be together and have at least a moment of happiness.
My personal take is "Mike" is supposed to be the Archangel Michael. But for my overall thinking, see above satetment...
