God created us in His image and gave us the power and right to choose. Angels and demons have the power to choose but NOT the right to choose.
Humans are given both and God honors our choices. If you choose to go to hell, God honors that but He is still speaking and calling us to eternal life.
There’s no more battle left for you to fight, Jesus has already defeated the devil and won the battle for us.
The only warfare we have is in the mind. The devil blinds the mind from believing. Pray for labourers to preach the good news; whoever is born of God overcomes the world. If you’re born again, you have the power.
