Something To Think About
Is God restricted in time like we are? Is it impossible for
God not only to slow elapsed time by high speed, but
to experience time in ways unknown to us? Psalms
90:4 says, "For a thousand years in your sight are like a
day that has just gone by, or like a watch in the night."
2 Peter 3:8 says, "But do not forget this one thing, dear
friends: With the Lord a day is like a thousand years,
and a thousand years are like a day." So it seems fairly
certain that God is not limited in time the way we are.
