Are you relying on your own righteousness? Or on ‘the righteousness of God which is by faith in Jesus Christ’? Do you know the grounds of your standing at this moment? Have you got this solid rock beneath you? Are you relying utterly upon the Son of God and His perfect work on your behalf? If not, you have not got the breastplate of righteousness, and that means that you are already defeated by the devil. This is the only righteousness that avails, not only when we go to God in prayer, but when we are confronted by the wiles of the devil, and as we wrestle against the principalities and powers, the rulers of the darkness of this world, the spiritual wickedness in high places.
