The author shares, 'Whenever I mention the "Grumble Fast", most respond with a nervous laugh. Yes, grumbling is human nature! But in the end-times, it will shackle us to increasing darkness and demonic defeat.' Holy Spirit is calling us higher to worship in the Throne room. How far worship warriors rise into glory realms will be proportional to their victory over grumbling. In the year and decade of pey, (the Hebrew word for mouth), our mouths need to be clean to boldly proclaim His Word! When we grumble: It becomes evident we have forgotten God's miracles; We are hindering our Messiah King; Jezebel and Leviathan are active and empowered; We may be destroying relationships, sleep, and health. Do the Scriptural Grumble Fast for 40 days to: Defeat habitual grumbling; Develop consistent gratitude; Speak heaven's language and create heaven's atmosphere; Invite El Shaddai into your circumstances; Outwit end-time traps-Jezebel and Leviathan; Enter your destiny; Position your heart to worship in the Glory!
