In the beginning, God made everything. He made the things we can see and things that we cannot see. He made spirits called angels. When He made the earth, they were there shouting with joy! God made the angels to serve Him and to honour Him.
But some of the angels rose up against God. And they became known as evil spirits. Their leader is Satan. He and his evil spirits are still working in the earth today. They work against God and God’s plans.
But God is still in control. He is stronger than all of the spirits that he created.
One day, God will judge Satan and his evil spirits. Then He will throw them all into a fire that never goes out.
