It did explain a lot but it's too late in the game to have episodes that don't involve te core cast.
I was off that bandwagon a loooooong time ago. But I do think the light is a little play on God.
It kinda does though. You have Smokey who desperately wants to leave the island (Jack in the very beginning), Jacob who wants to go but can't (Locke in the beginning) so there is a dichotomy there and now the roles have been reversed where Jack is acting the 'Jacob' part and Locke is literally Smokey.
Oh and it's not God until he tells Kent to stop playing with himself (Real Genius reference).
