Exodus 19:16,18 - And it came to pass on the third day in the morning, that there were thunders and lightnings, and a thick cloud upon the mount, and the voice of the trumpet exceeding loud; so that all the people that [was] in the camp trembled. Exd 19:18And mount Sinai was altogether on a smoke, because the LORD descended upon it in fire: and the smoke thereof ascended as the smoke of a furnace, and the whole mount quaked greatly.

Revelation 16:18 - And there were voices, and thunders, and lightnings; and there was a great earthquake, such as was not since men were upon the earth, so mighty an earthquake, [and] so great.

Notice when God shows up, His arrival is accompanied by "voices, trumpets, thunder, lightning, and earthquakes".

I believe when God leaves the Spiritual dimension to enter our physical dimension, he bends the fabric of these dimensions which cause disturbances to our surroundings.

Notice in 2nd Samuel 22:10 and Psalm 18:9 - He bowed the heavens also, and came down; and darkness [was] under his feet.

God bowed the heavens. If you continue reading in 2nd Samuel 22 and Psalm 18, you will also read what accompanies this "bowing of the heavens" is thunder, lightning, voices, and smoke.

This happens in every occurrence where the Lord opens this doorway.

Now look at Exodus 34:30 - And when Aaron and all the children of Israel saw Moses, behold, the skin of his face shone; and they were afraid to come nigh him.

Keep in mind that Moses was on "a high mountain" when this took place.

Matthew 17:1-3 And after six days Jesus taketh Peter, James, and John his brother, and bringeth them up into an high mountain apart, And was transfigured before them: and his face did shine as the sun, and his raiment was white as the light. And, behold, there appeared unto them Moses and Elias talking with him.

Once again, we see Jesus on "a high mountain" and this "bowing of the heavens" affected Jesus and Moses in the same manner.

Exodus 34:28 - And he was there with the LORD forty days and forty nights; he did neither eat bread, nor drink water.

Moses probably didn't even realize he was there 40 days. To him, it was but a brief moment in time when the heavens were bowed, and he stepped onto the mount to speak with Jesus, Peter, James, and John.
