Therefore, take up the full armor of God, so that you will be able to resist on the evil day, and having done everything, to stand firm. -Ephesians 6:13 NASB

Since we are fighting against spiritual forces of wickedness, we need to have on—our spiritual protection with its weapons—the full armor of God. To resist a demonic attack, we cannot run away from the battle, but must face them head on—standing our ground.

The full armor of God is our only defense against such evil. If we don’t put it on, we will be defeated, putting our faith in danger.
