Isaiah 10

For God a day is as a thousand years. He can accomplish in one day all that He wants to do.

Nations make plans to achieve their goals. They may have a one year/five year/100 year plan. This must amuse the Lord. The One enthroned in heaven laughs; the Lord scoffs at them. [Ps. 2:4]

He created the world as we know it in 6 days. All He needs is one day to do whatever He wants.
