Warfare has to do with the mind, and everything we receive from God is by faith, which is the reason the book of Jude exhorts us to "contend for the faith", fight for justification by faith. Â Contend not to come under condemnation, know you are the righteousness of God in Christ Jesus. Â The devil would like you to move from your position. What he doesn't realise is that righteousness is a gift, therefore, we can't be more, because it didn't come from us in the first place.
