Remember each phrase in these first five chapters of Rev. are invitations to encounter in the knowledge of God. Chapters four and five relate to the throne of God. The bible says Holy Spirit takes the deep things of God and makes them known to us, but we must ask. If we keep knocking on these doors (phrases) and it will be opened to us. We ask for a Eph 1:17 Spirit of Revelation. Each verse is calulated by the Holy Spirit and details something about the heart of God.
Fasting doesn’t earn you more, but it does accelerate the process. Let the written word take you to the Living Word. The first four books of Revelation are meant to be prayed, prayer dialouge and revelation with Jesus through the Spirit. This will strengthen us to stand in what’s coming, and set are hearts on fire now, connecting us to God. Hunger and persistance are neccesary.
