Brian Guerin delivers a powerful sermon on 'Hidden Manna,' emphasizing the importance of intimacy with God and the necessity of hearing His voice in a personal and profound way. He highlights Revelation 2:17, where Jesus promises hidden manna to those who overcome, urging the congregation to seek a deeper relationship with God through humility and proximity. Guerin warns against complacency in faith, encouraging believers to lean in and listen closely to the whispers of the Holy Spirit, as the time for playing church is over. He stresses that true transformation comes from the hidden, divine bread that God offers to those who earnestly seek Him. The sermon calls for a fresh commitment to prayer and the secret place, where believers can receive their new identity and authority from God.
