Decrees are commands that set boundaries. Decrees divide/cut/judge in a powerful agreement.

In His Living Word, the Lord declares what He wants to do in the earth. We are the ones He wants to use! (Psalm 24:7) When you make a decree, you are agreeing with His words and adding your 'yes and amen' (using your authority as a son/daughter of God). That is one way that we rule and reign with Him.
