You have no scripture, so you have no defense for what you believe. I have raised three children, everyone of them was evil.You lie about what the Bible says.
Nowhere IN THE BIBLE can you find people being CREATED with "the Spirit of the devil" in them. That is some evil nonsense that you dreamed up.
Your approach to the Bible is very cultish.
"For the imagination of a man's heart is evil from his youth" Genesis 8:21.
"There is none righteous, no, not one" Romans 3:10.
Adam is our first father. We have inherited his sinful, evil nature that is of Satan.
