In the fourth book of the Psalms, Psalms 90-106, we find the theme of the brokenness of the world, including human mortality, in the context of God’s sovereignty.
They teach us that none of us are able to make our own life, never mind the whole world, as it should be. They teach that we will suffer but we can’t protect those we love closest to us from suffering either.
"Therefore, I urge you, brothers, in view of God’s mercy, to offer your bodies as living sacrifices, holy and pleasing to God—this is your spiritual act of worship."
