Ephesians 6:12

12 For our struggle is not against flesh and blood, but against the rulers, against the authorities, against the powers of this dark world and against the spiritual forces of evil in the heavenly realms.

James 3:14-16

14 But if you harbor bitter envy and selfish ambition in your hearts, do not boast about it or deny the truth. 15 Such “wisdom” does not come down from heaven but is earthly, unspiritual, demonic. 16 For where you have envy and selfish ambition, there you find disorder and every evil practice.

1 Peter 5:8

8 Be alert and of sober mind. Your enemy the devil prowls around like a roaring lion looking for someone to devour.

Luke 10 :18-20

18 He replied, “I saw Satan fall like lightning from heaven. 19 I have given you authority to trample on snakes and scorpions and to overcome all the power of the enemy; nothing will harm you. 20 However, do not rejoice that the spirits submit to you, but rejoice that your names are written in heaven.”
