The first thing is to "go through the open door"! To recognise who is inviting us and providing the door to enter, Christ Himself. To view almighty God, the Father Himself. To take in the holiness and awe. What the various things mean, fire, trasluscent, To allow ones eyes to take in , the rainbow, of His promise to us. The four living creatures capturing the whole of the created order, That super nature, angels are key here, but Earth is just as much part of the scene.
We join the elders and can
Sing
Prostrate ourselves
Take off our crowns and surrender.
Sing even new songs !!!
Wait in silence!!!!
