What all of these smart people are missing in their thinking is the God particle. God is every where and created every thing. His will is playing out in front of all of us everywhere.
If they would only read his owners manuel they would have a better understanding of what is ahead of us. He even warned of these people worrying about these things in these end times. His reply, all things are in His care to be played out according to His plan. Told to those who have ears to hear from the begining.
This is not the end of the world, but the end of this earth age. Just as the dinos had their earth age a new earth age is dawning upon us. In this new earth age only those whom are found worthy will servive.
We are saved by His grace. Confirmed in our faith by His wisdom.
He is the same today, yesterday and tommorrow. His will does not change. But you can. To servive you must get into His will.
And, it is as simple as that ! ;~)
