Hello, John and Doves,
 
What is the "twinkling of an eye?"  [Please read 1 Corinthians 15:51-58.]
 
I believe it is the length of time it takes for visible electro-magnetic energy [light] to change direction at some boundary of the cornea.  When light changes direction, a "twinkling" occurs.  How long is that transition?  Well, it is like a step function in mathematics, ideally.   Therefore, the time approaches zero, exactly.
 
Now, think of this:  How much time is there between New Year's Eve [when people wish each other "peace and safety"--1 Thessalonians 5:3] and New Year's Day?
 
Let me give you a hint:
        "For the righteous LORD loves justice.
            The virtuous will see His face."  Psalm 11:7
 
        "Help, O LORD, for the godly are fast disappearing!
            The faithful have vanished from the earth!"  Psalm 12:1
 
The Jewish concept of Heliacal Time can explain why I think Psalm 11 and Psalm 12 apply to our day.
