SERPENT SEED
The Word says that Eve was beguiled by the serpent. She was actually seduced by the serpent. Satan took advantage of the serpent's physical characteristics to use him to beguile Eve. Remember that it was Lucifer’s ambition to build himself a greater kingdom than Michael did in heaven, before he was kicked out on earth. And still, he wanted to pursue his evil plan in this world after that. And the only way for Satan to accomplish what he wanted to do was to enter the serpent in Eden even as he entered by evil spirits into the swine at Gadara. He could not have a child directly by Eve as did God by Mary, so he entered into the serpent and then beguiled Eve. He seduced her and by her did Satan have a child vicariously - CAIN, the seed of the serpent, who bore the full spiritual characteristics of Satan and the animalistic (sensual, fleshly) characteristic of the serpent, and a murderer, too.
