A few months ago I read the book, Why We Sleep. I read it based on the recommendation of someone. My disclaimer for the book is that the author believes in evolution and throughout the book talks about how humans have evolved to this point.

The book was full of studies of what happens when people do not get enough sleep. There were studies of how after learning something people then sleep and how the sleep helped them to retain what they had learned. One study showed how the lack of sleep impaired reactions for driving at the same level as alcohol.

The first mention of sleep in the Bible was when the Lord put Adam to sleep and created woman. (Genesis 2:21)

A deep sleep fell on Abram. While asleep God speaks to him foretelling what will happen to his offspring. (Genesis 15:12) God had already given Abram the promise but reminding him.

It was while Samson was sleeping that Delilah cut his hair. (Judges 16:1-22)

God calls to Samuel while he was lying down. (I Samuel 3). I think that is a time when we are quiet and still.

Being awake at night at times can be part of God’s plan. That happened to the king. He couldn’t sleep so he had the book of memorable deeds read to him. He remembers what Mordecai had done. (Esther 6:1)

Psalm 4:8 “In peace I will both lie down and sleep for you alone, O Lord, make me dwell in safety.” (ESV) We can sleep when we feel safe and that comes from the Lord.

We are warned not to sleep if we have done something wrong to your neighbour. (Proverbs 6:1-4)

Ecclesiastes 5:12 sleep is sweet to the labourer. I agree with that. At the end of a busy day of work it is sweet to go to bed and sleep.

Sleep is also used in the Bible to refer to those to death.

There are also numerous passages about dreams in the Bible. God often spoke in dreams.

So a quick summary. God is the one who gives sleep and there are times that he keeps us awake. We were created to need sleep. God does not need sleep (Psalm 121:4) but we need it. Get the sleep that you need.

Are you getting the sleep you need?
