The Serpent Seed Doctrine, aka The Two Seedline Doctrine. Is Adam really Cain’s Father? You may understand the Bible to say Adam and Eve had sex and Cain was born of that union. That’s an assumption this writing will challenge. This is important because, as I think you’ll shortly see, unless you really grasp the importance of seed and what happened in the Garden between the serpent, Eve and Adam you’re missing a major “piece of the puzzle.” Without it, you won’t be able to interpret some really important elements of the counterfeit and the genuine agendas playing out in these last days. Adam did not father Cain, the serpent did.
