The battle for Christians is in the mind. Thoughts believed become spirit. God has given us armor to protect us in this thought life battle. Righteousness is the first thing to seek, and the first thing the devil wants to take from you. If he can get your righteousness he can inflict a terrible wound. The devil always wants Christians to base their righteousness on their own performance. Your performance will never qualify you to be righteous. Even if you had a a perfectly flawless performance and never sinned but one time you would be disqualified. The bible says Jesus is our righteousness. When the priests took the lamb before the sacrifice in the temple they examined the lamb for the flaws not the person bringing the lamb. If you start talking to the devil about anything righteousness related that relies on your performance you loose. The only righteousness that exists for human kind is the blood of Jesus Christ. Their is no human righteousness. If you messed up then put it under the blood and use your breastplate.
Joseph prince quote:
“I believe that right believing leads to right living. You cannot set yourself free from condemnation by self-efforts. But when you believe the finished work of Jesus has made you righteous in God’s eyes, you receive His power to reign over your negative circumstances and live the abundant life.
Condemnation kills, but the Spirit gives life! Always look to the finished work of Jesus who paid the price for your freedom. Look and live!”
