Finally, let the mighty strength of the Lord make you strong. Put on all the armour that God gives, so you can defend yourself against the devil's tricks. We are not fighting against humans. We are fighting against forces and authorities and against rulers of darkness and powers in the spiritual world. So put on all the armour that God gives. Then when that evil day comes, you will be able to defend yourself. And when the battle is over, you will still be standing firm.
