This question assumes that God is somewhat human and requires sleep. Some will dispute that even from the days of creation that God had to rest after 6 days of creating earth, which therefore “proves” he must take time off.
However, if we read
By the seventh day God had finished the work he had been doing; so on the seventh day he rested from all his work. – Genesis 2:2
There is no evidence that God needed to rest, only that He did rest. Other people point to:
for in six days the Lord made the heavens and the earth, and on the seventh day he rested and was refreshed. – Exodus 31:17b
Here, again, there is only evidence that suggests that rest was involved following creation, but not that it was necessary for God. Rest implies that God stopped, took a break. The Scripture also states that God was refreshed, but refreshed could be translated as “energized” or “invigorated” meaning that God felt great upon seeing His creation.
Isaiah 40:28 clearly tells us:
The Lord is the everlasting God,
the Creator of the ends of the earth.
He will not grow tired or weary,
and his understanding no one can fathom. – Isaiah 40:28b
So, if you think God is taking the day off, I would assume you are wrong. God doesn’t take vacation; He watches at all times!
3 He will not let your foot slip—
he who watches over you will not slumber;5 The Lord watches over you—Psalm 121: 3, 5
