“Unless the Lord builds the house, its builders labor in vain.

Unless the Lord watches over the city, the watchmen stand guard in vain.

In vain you rise early and stay up late, toiling for food to eat

for He grants sleep to those He loves.”

 

So it is right to labor and stand guard, to rise early and stay up late, toiling for food to eat - when the Lord is building and working for us. It is also right to rest because the Lord grants sleep to those He loves - He takes care of those He loves while they sleep, they need not to worry about toiling for their food. Sounds a lot like the sabbath to me. I believe it is important to sit back every once in a while and reflect on this verse and our lives: Is God building the house or am I toiling with my own efforts without Him?
