The document discusses surrendering fully to God and allowing the Holy Spirit to work without restriction in one's heart. It states that this passion and love for God is fueled by letting Him become greater while we become less. When filled with God, genuine joy from Him satisfies the soul in a way that nothing else can. The document prays that God would set people on fire with consuming passion and love for Him, and that the Holy Spirit would overtake all they are. It asks God to come and fill them, remove anything not of Him, refine and purify them, so their hearts yearn only for Him.
