So many Spirit-filled believers and Kingdom heirs go through life defeated and never fulfill their destinies because they don't know where the war is in their lives. They don't know where the battle ground is. Many believe that their failures and defeats come from bad luck, bad timing, bad family back ground, and other negative circumstances. In actuality, they don't understand that their failures and defeats in life come as a result of losing the war in the mind. Some don't realize that there even is a war! Make no mistake - there is a war, and you have an enemy. Revelations 12:9-12
The evil one lost his fight in the heavens and got tossed out onto the earth. As a result, he's desperate to destroy the lives of God's highest creation - mankind. However, God sent Jesus to redeem mankind and empower us to defeat the devil! John 10:10, Luke 10:19
Jesus gave us authority over all of Satan's power. So why are we still at war? Satan knows that Jesus came so we could have life and have it more abundantly. Satan, on the other hand, comes to steal, kill and destroy what Jesus has already died for us to have. If he can steal, kill or destroy our concepts of Jesus' finished work in our thought life, then he can steal from, kill and destroy anyone. The only real weapon that Satan can use against believers is deception.
This is because the devil is absolutely powerless. And deception begins in the mind, in the thought patterns of unsuspecting believers.
