The fight is not against man.

A key point to remember that God's Word teaches us is found here:

Ephesians 6:12 

12 For we do not wrestle against flesh and blood, but against the rulers, against the authorities, against the cosmic powers over this present darkness, against the spiritual forces of evil in the heavenly places.

Our battle in not against man. Our battle is against Satan and his demonic forces. For a man is either born again through the the shed blood of Jesus Christ and following Him as Lord and Savior or he is following the Satan and controlled by him. There is no in between road.

So what is the key to victory.....Jesus and Jesus alone! Only a man that has Jesus can have the victory in life.
