could the prophecy of the little book be the prophecy of the Psalms? The Psalms for the most part are prayers of prophecy concerning the Son and His earthly life and how He experienced what He went through to save us. Seems like that is well deserving of a mighty Angel holding them up above the earth.
Remember just before there is a sealed book that can’t be opened by anyone no one is worthy ?
“And I saw in the right hand of him that sat on the throne a book written within and on the backside, sealed with seven seals. And I saw a strong angel proclaiming with a loud voice, Who is worthy to open the book, and to loose the seals thereof? And no man in heaven, nor in earth, neither under the earth, was able to open the book, neither to look thereon. And one of the elders saith unto me, Weep not: behold, the Lion of the tribe of Juda, the Root of David, hath prevailed to open the book, and to loose the seven seals thereof.”
Revelation 5:1-3, 5
The lamb takes the book and opens the seals of the book because he has been found worthy though no one else was the lamb who was slain opens this sealed book through chapter 6-8
Now the book has been opened and isn’t sealed anymore it’s open for all to read all nations and peoples now John the apostle is handed a little open book and sent to prophecy to the nations
“and
he had in his hand a little book open: and he set his right foot upon the sea, and his left foot on the earth, And the voice which I heard
from heaven spake unto me again, and said, Go and take the little book which is open in the hand of the angel which standeth upon the sea and upon the earth. And I went unto the angel, and said unto him,
Give me the little book. And he said unto me,
Take it, and eat it up; and it shall make thy belly bitter, but it shall be in thy mouth sweet as honey. And I took the little book out of the angel's hand, and ate it up; and it was in my mouth sweet as honey: and as soon as I had eaten it, my belly was bitter.
And he said unto me,
Thou must prophesy again before many peoples, and nations, and tongues, and kings.”
Revelation 10:2, 8-11 KJV
If you look back to prophecy you find God saying of the law and judgement and israel “ it’s like you have a book that is sealed and no one can look at it or read it , you say to others read me the book so I may know , but your vision and sight is like the book is sealed and none of you can look upon it “
then you think about it who fulfilled the old covenant that no one else could ? And who gave the new testement and sent it to all nations ?
Are the two books actually the same book one place it’s sealed and can’t be opened then Jesus appears and it’s later opened and given back to men open and no longer sealed ?
