Our mind is full of thoughts all of the time. But who we allow to control our thoughts is up to us. Either God or Satan will take control of our thoughts. The Holy Spirit can free us from uncontrolled thoughts. It's the idea of replacement-whatever you want to change in your life, don't resist it; replace it. We should ask the Holy Spirit to give us new ideas to think about that will replace the old, bad thoughts. When you think of something from God's word, Satan's negative thoughts must leave. So, invite the Holy Spirit to have free access to your mind to replace bad thoughts.
