Ephesians 6:11-12. Put on the whole armor of God, that you may be able to stand against the wiles of the devil. For our wrestling is not against flesh and blood, but against the principalities, against the powers, against the world’s rulers of the darkness of this age, and against the spiritual forces of wickedness in the heavenly places.
Isaiah 14:12-15. How you have fallen from heaven, morning star, son of the dawn! How you are cut down to the ground, who laid the nations low! You said in your heart, “I will ascend into heaven! I will exalt my throne above the stars of God! I will sit on the mountain of assembly, in the far north! I will ascend above the heights of the clouds! I will make myself like the Most High!” Yet you shall be brought down to Sheol, to the depths of the pit.
