Indications of the Sixth Seal being opened:
Great Earthquake
Sun darkens, turns black
Moon as blood
Stars fall onto the Earth
Heaven disappears like a scroll rolled together
Every mountain and island move out of their places
All people terrified and hide themselves from God Almighty
They want the rocks to protect them from Jesus’ wrath
Who can stand before God?
And I beheld when he had opened the sixth seal,
and, lo, there was a great earthquake;
and the sun became black as sackcloth of hair,
and the moon became as blood; Revelation 6:12
The sun shall be turned into darkness, and the moon into blood,
before the great and the terrible day of the Lord come. Joel 2:31
And the stars of heaven fell unto the earth,
even as a fig tree casteth her untimely figs,
when she is shaken of a mighty wind. Revelation 6:13
And all the host of heaven shall be dissolved,
and the heavens shall be rolled together as a scroll:
and all their host shall fall down, as the leaf falleth off from the vine,
and as a falling fig from the fig tree. Isaiah 34:4
And the heaven departed as a scroll when it is rolled together;
and every mountain and island were moved out of their places. v 14
So that the fishes of the sea, and the fowls of the heaven,
and the beasts of the field, and all creeping things that creep upon the earth, and all the men that are upon the face of the earth, shall shake at My presence, and the mountains shall be thrown down, and the steep places shall fall,
and every wall shall fall to the ground. Ezekiel 38:20
And the kings of the earth, and the great men, and the rich men,
and the chief captains, and the mighty men,
and every bondman, and every free man,
hid themselves in the dens and in the rocks of the mountains; Revelation 6:15
And said to the mountains and rocks,
Fall on us, and hide us from the face of Him that sitteth on the throne,
and from the wrath of the Lamb: Revelation 6:16
The mountains quake at him, and the hills melt,
and the earth is burned at his presence,
yea, the world, and all that dwell therein. Nahum 1:5
Who can stand before His indignation?
and who can abide in the fierceness of his anger?
His fury is poured out like fire,
and the rocks are thrown down by him. Nahum 1:6
For the great day of his wrath is come; and who shall be able to stand?
Revelation 6:17
The Lord is good, a strong hold in the day of trouble;
and He knoweth them that trust in Him. Nahum 1:7
