Ephesians 6:12 says, “Our struggle is not against flesh and blood but against rulers, authorities, the powers of the dark world and against the spiritual forces of evil in the heavenly realms.”
You need to know that the devil has your number. Recognize that he works against you. In reading Believe That You Can by Jentezen Franklin, I came across this teaching I wanted to share. Picture the devil calling a board meeting with his chief demons, “What is our greatest weapon against this person?” Some of the demons suggested lust or greed or the usual things. And then one of them said, “Our greatest weapon against the believer is discouragement.” And that’s what he uses to make you quit, especially right before you’re about to run through the finish line.
Next time you feel discouraged, don’t quit.
All it means is that the devil is so desperate to stop you that he sent his most powerful weapon against you. You should stand up and start praising God for discouragement. Say, “Thank You, Jesus! Thank You God! I must really bothering the devil, and I must be getting close to something—because I am so discouraged!”
The devil doesn’t know what to do with a child of God who talks like that. You just took hold of the very thing he tried to mess you up with, and you turned it around. You just get encouraged about your discouragement.
