Dear Doves
I can't come up with a satisfactory answer to this unless it's a mis translation from the original Hebrew.

In Rev it says "and they serve Him day and night in His temple".
However, we are told there is no night in heaven or no darkness. Can someone shed light on this? (pun intended)! It's been niggling at me for some reason- probably because I take all scripture literally. Thanks all
Lovingly ysiC Susan
