Worship can only be fuelled by revelation. True revelation of God brings us into a place of reverent awe of Him and an understanding of who we are in the light of who He is. Although facedown is a physical posture where the worshiper prostrates before God, it is a spiritual position we must live day in and day out of reverent submission of His Kingship. Facedown is a symbol of total surrender and helplessness. The King identifies with His subjects when they are bowed down at His arrival and He looks on at all that belongs to Him.
When we worship God, we must reverence him in revelation of how mighty He is and how insignificant we are. God is the King of the universe and all creation inevitably bows down before His Majesty. Jesus is the King of all Kings and Lord of all Lords (Rev 17:14, 19:16,) and the scripture says that “One day, every knee will bow and every tongue will confess to Him (Isa 45:23, Rom 14:11, Phi 2:10).” That is the future.
The Hebrew word is Shachah or Hishtahawa (Ugaritic) which is Proscuneho (Greek) which is Weorthscipe which when translated into English is Worship.
