Isaiah 53:5

Be He was wounded for our transgressions, he was crushed for our wickedness (our sin, our injustice, our wrongdoing); the punishment (required) for our well-being fell on Him, and by His stripes we are healed. 

The devil wants us to think we have to pay the price for sin, but we need to remind him that Jesus paid it already. We don’t have to bear what Jesus already bore with His wounds on the cross. We speak the words of the bible out loud. We remind the devil of the power and authority of our God in and over our lives.
