KU,
there was ALREADY an ARK in Heaven = remember, God used and uses the physical to represent the Spiritual/Heavenly...
He for sure used 'the earthly waters' to represent The Holy Spirit...
REV. 11:19.
And the Temple of God was opened in heaven, and there was seen in His Temple the ark of His testament:
and there were lightnings, and voices, and thunderings, and an earthquake, and great hail.
HEB. 8:5.
Who serve unto the 'example and shadow of heavenly things', as Moses was admonished of God
when he was about to make the tabernacle:
for, See, saith He, that you make all things according to the pattern showed to you in the mount.
in other words; the physical Tabernacle represents the Spiritual Tabernacle in Heaven, it is but a
shadow of things to come'...
