Once again, Science is in line with the scriptures. In this case, the Science is in the form of one of the most brilliant Scientific minds of our era, Stephen Hawking. Hawking came out recently saying we need to abandon earth or face extinction. Pretty strong, sobering words coming from a very smart guy. In fact he's advocating we act fast.
Reminds me of the question posed to Jesus, another brilliant mind, by his disciples. "What will be the sign of your coming and the end of the age?"
The answer and description given by Jesus, and then later by John in his vision on the isle of Patmos, is not far off from where Hawking is coming from. In other words, just like the "circle of the earth" and "the earth hangs on nothing" another biblical truth comes to light via the Scientific world showing us that God gave us some very important scientific answers all along.
Biblically speaking, the end of the age will start with a cosmic disturbance. The signs will be in the heavens. Many have mentioned astroids as being the destructive means by which this may happen. Some say nuclear bombs will be our undoing.
The bible is clear about this cosmic disturbance that will usher in the end. It says "the sun shall be turned into darkness and the moon into blood, before the great and terrible day of the Lord comes." Joel 2:31
and...
"there was a great earthquake and the sun became black as sackcloth of hair, and the moon became as blood: and the stars of heaven fell to the earth even as a fig tree casts her untimely figs when she is shaken of a mighty wind. And the heaven departed as a scroll when it is rolled together and every mountain and island were moved out of their places." Rev 6:12-14
Of course, Hawking has given us his view, sans scripture, but both are saying pretty much the same thing. There's coming a day when we will go from one age to another or we will face extinction on this earth. In Hawking's view he's suggesting we explore space for alternative habitation. In God's Word it says he will usher in a "new heaven and a new earth."
There are many signs that show us that the time is drawing near. Look at what's going on in the animal kingdom. Look at mankind and the hatred, greed and violence that is permeating our culture by the hands of many. The weather and climate is but just another thing to watch. The diseases and pestilences as well. All are going to get expedientially stronger until we can't ignore it any longer. I can't pick up the daily newspaper and not wonder how long do we have?
Only God knows.
Our job is to be ready.
