The Bible Ends with Revelation and begins with Genesis.

Revelation foretells the end of the Earth and humankind.

That end begins with a sacrificial lamb carrying a holy scroll. As the lamb breaks a series of seals on the scroll, stuff (much of it bad) happens. After the seventh (final) seal is broken, all Hell breaks loose (in a manner of speaking). The angels in the trumpet section start blowing. The first 5 blasts bring on the destruction of the Earth. It gets worse.

Hold it right there, Chester!

In the beginning (Genesis) God almost destroyed the Earth and all of humankind.

It seems that God had become irritated by the human species. In retaliation for people's wickedness, he destroyed the Earth as we knew it, and wiped out all animal life - except the Noahs and their menagerie (one male and one female of each species).

After the flooding stopped and things calmed down, God told Noah to go forth and multiply (on the Earth). As they started to settle in, Noah gave God burnt offerings of some of the beasts he had saved. Note that in performing those sacrifices, Noah caused the extinction of some species. But I digress.

God was impressed by the wiping out of several species. In return, he made a promise (or more precisely, a covenant):

"Never again will I curse the ground because of man, even though every inclination of his heart is evil from childhood. And never again will I destroy all living creatures, as I have done. As long as the earth endures, seedtime and harvest, cold and heat, summer and winter, day and night will never cease." (Genesis 8:21-22)

Just in case Noah (or future generations) might doubt his sincerity, God sealed the deal with a rainbow.

"I establish my covenant with you: Never again will all life be cut off by the waters of a flood; never again will there be a flood to destroy the earth."

And God said, "This is the sign of the covenant I am making between me and you and every living creature with you, a covenant for all generations to come: I have set my rainbow in the clouds, and it will be the sign of the covenant between me and the earth. Whenever I bring clouds over the earth and the rainbow appears in the clouds, I will remember my covenant between me and you and all living creatures of every kind. Never again will the waters become a flood to destroy all life. Whenever the rainbow appears in the clouds, I will see it and remember the everlasting covenant between God and all living creatures of every kind on the earth."

So God said to Noah, "This is the sign of the covenant I have established between me and all life on the earth." (Genesis 9:11-17)

We have a deal, signed, sealed, and delivered.

If things go as the Book of Revelation predicts, it means that God reneged on the deal he made with Noah and all future generations.

'Splain me that.
