As I get older one of the Psalms that is growing as one of my favorites is Psalm 90, the first Psalm written and penned by Moses, the man of God. It is a overview of the life of humans, the impact of our sins on God, the futility of associating time and God, and the importance of counting our days as temporal. The line that always kills me is, "Our hidden sins are revealed in the light of your face."
Here it is in its entirety.
"Lord, you have been our dwelling place throughout all generations.
Before the mountains were born, before you gave birth to the earth and the world,
from eternity to eternity you are God.
You grind people to dust, and you say, “Return, children of Adam.”
For a thousand years in your sight are like a day, like yesterday that has gone by,
or like a watch in the night.
