As I write this, here in Michigan it is 10:25 AM, December 31, 2011. At this very time in Australia it is already New Years Day, January, 1, 2012.
Time is relative. God said so when He had Peter remind us that to the LORD a day is as a thousand years and a thousand years is as a day.
Bodies of matter move in relation to one another and we percieve that movement as time.
Jesus revealed Himself to the Apostle John as the Alpha and Omega. He determines the times. He coordinates the movements of those bodies of matter in whose relative movements in relation to one another we percieve this thing we call "time"..
Our times are indeed in your hands O LORD!
