"For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places." (Ephesians 6:12)
One cannot wrestle in prayer unless you have put off the old man and have put on the new man. The new man in Christ will not only put on the whole armor of God, but will use the armor.
Be renewed in your mind and put on the new man. Our battles begin with the flesh and we conquer the flesh through prayer, self-denial, the Word of God, and obedience. The saints are those who put on the whole armor and have put off the old man and have put on the new man.
