Do we. NEED to know everything? I dont think so. God has perfect right to keep things mysterious and constantly surprising us.
1Corinthians 2:9
But as it is written, Eye hath not seen, nor ear heard, neither have entered into the heart of man, the things which God hath prepared for them that love him.
Here is a strong hint that when we are no longer confined to the planetary world and become like angels then there are even more surprises in store for us.
The Earth at the time of its creation must have been extremely wondrously beautiful to behold (even today there are patches of great natural beauty remaining).
The heavenly realm must be truly awesome. A world of light, and crystal, and beauty that is at the moment beyond our comprehension.
Angelic beings, and strange beasts - Ezekiel, Isaiah and Revelation give glimpses - just to tease us enough to inquire and desire:
Revelation of Jesus Christ 4:2-4
And immediately I was in the spirit: and, behold, a throne was set in heaven, and one sat on the throne. And
he that sat was to look upon like a jasper and a sardine stone: and there was a
rainbow round about the throne, in sight like unto
an emerald.
And round about the throne were four and twenty seats: and upon the seats I saw four and twenty elders sitting, clothed in white raiment; and they had on their heads
crowns of gold.
Revelation of Jesus Christ 4: 5-11
And out of the throne
proceeded lightnings and thunderings and voices: and there were seven lamps of fire burning before the throne, which are the seven Spirits of God. And before the throne
there was a sea of glass like unto crystal: and in the midst of the throne, and round about the throne,
were four beasts full of eyes before and behind. And the first beast was like a lion, and the second beast like a calf, and the third beast had a face as a man, and the fourth beast was like a flying eagle. And the four beasts had each of them
six wings about him; and they were
full of eyes within: and they rest not day and night, saying, Holy, holy, holy, Lord God Almighty, which was, and is, and is to come. And when those beasts give glory and honour and thanks to him that sat on the throne, who liveth for ever and ever, The four and twenty elders fall down before him that sat on the throne, and worship him that liveth for ever and ever, and cast their crowns before the throne, saying, Thou art worthy, O Lord, to receive glory and honour and power:
for thou hast created all things, and for thy pleasure they are and were created.
