Ephesians 6:12-13

12We are not fighting against human enemies. Instead, we are fighting against the rulers and the powerful spirits that have authority over this dark world. We are fighting against the bad spirits who live in the heavens.

13Because of that, take all the help that God gives, like it is your armour. Then, when the bad time comes, you will be able to stand strongly. You will not fall. After you have finished everything, you will still be standing strongly in your place.
