Also, along with mikefloods coment, is that angels were presumably around for million, if not billions of years with God and Jesus, up in heaven.
The were contemporaries of them, as fellow spiritual creatures. They not only witnessed the complete creation of the physical UNIVERSE, with all the galaxies, suns, solar systems, earth, animal, plant life, and humans, but also lived in the spiritual realm with them.
For them to have disobeyed, and forsaken their natural forms, is quite a stretch, and baffling. Then for Adam and Eve to have been tempted RIGHT AWAY, after their creation, and held to such a high standard, when they were really only INFANTS, in the big scheme of things.
So, perfect angelic creatures, who LIVE with GOD, and have been around for billions of years, sinned ONLY then, and get a slap on the wrist, and allowed to MOLEST the 2 newest creatures, human man and woman. Meanwhile, they were only children in comparison, both age wise, mentally, and an inferior creature, compared to an ANGEL. Yet now for eating a F@CKING fruit, have to deal with death, misery, disease, pain, shame, and all the evils of the world.
If you were God, or a parent, would you let some godlike all powerful creature, with powers, and intellect beyond imagining, with cunning, and ill intent, tamper or harass your NEWBORN BABY. No, you would NEVER do that. Yet, by God allowing Satan to molest/tamper with Adam and Eve, thats EXACTLY what happened, if you really think about it. Then would you blame the BABY for being seduced and hurt, or would you have protected that baby. Adam and Eve were new "babies" when compared to the millenia of spiritual creatures, and their time on planet earth.
