Satan/Draft

The satan is a spiritual being who is the leader of the rebellion against God. While we are never told his name, he is referred to with multiple titles that reveal different qualities and behaviors such as "the satan", "the devil", "the great dragon", and "that ancient serpent". His mission, as identified by Jesus, boils down to "to steal and to kill and to destroy."

He led a third of the other spiritual beings into rebellion with him, then tricked Adam and Eve into joining this rebellion. With Adam and Eve choosing to rebel with him, the satan took their authority over all creation for himself, acting as the god of the earth. He has always accused the children of God of wrongdoing. He roams throughout the earth, walking as a roaring lion, seeking whom he can devour.

It was revealed to the Apostle John that the satan would indeed be defeated in the end. The archangel Michael and his angels will wage war with the satan and his angels, resulting in the rebels being cast out of heaven. Later, the satan will gather together the inhabitants of the world to Armageddon, but his kingdom — Babylon — will be destroyed and Jesus will come and destroy his armies. The satan will then be bound for a thousand years in the Abyss, only to be released and lose in battle again and be cast into the lake of fire and brimstone.
