Thank you G,
I knew that you have a heart of gold.
The beast coming out of the sea is the wicked leader (beast) coming forth from mankind (sea). Thus, in the Book of Revelation any reference to the sea is a reference to the followers of this wicked leader. And example of this is in Chapter Sixteen where the followers of the beast of the sea are condemned (Rev. 16:3).
3And the second angel poured out his vial upon the sea; and it became as the blood of a dead man: and every living soul died in the sea.
Another example is Rev. 10:2 where the angel stands with authority over the earth and the sea meaning that he has authority over the followers of the Rev. 13:1 beast and the followers of the Rev. 13:11 beast.
2And 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,
I realize these things are hard to see but if you keep and open mind then it may be given to you.
Thus, in Rev. 8:7 both the beast of the sea and the beast of the earth rise (Rev. 13:1 and Rev. 13:11).
7The first angel sounded, and there followed hail (Rev. 13:11)
and fire (Rev. 13:1)
mingled with blood (mankind)
and they (hail and fire)
were cast upon the earth (upon the world stage)
: and the third part of trees (leaders)
was burnt up and all green grass (followers)
was burnt up (lost their salvation in Christ by following Lucifer's two leaders)
And next in Rev. 8:8-9 we see the actions of the Rev. 13:1 beast.
8And the second angel sounded, and as it were a great mountain (a great nation)
burning with fire (burning with the actions of the 13:1 beast from 8:7 above)
was cast into the sea (cast into servitude of the 13:1 beast, Rev. 18:21)
: and the third part of the sea became blood (the followers of the 13:1 beast)
; 9And the third part of the creatures (people)
which were in the sea (following the 13:1 beast)
, and had life (had life in Christ)
, died (died the eternal death Rev. 12:4)
; and the third part of the ships were destroyed The destruction of this nation includes the destruction of its ships which is its navy.
I realize that reading the metaphors is not easy but some day you may decide to do that.
