What does the Bible say about the source of grief?

In Lamentations 2:32, it is affirmed that 'though he cause grief, yet will he have compassion.' This passage reveals that God, while being the ultimate cause of all events, uses grief as part of His providential workings. Grief and afflictions are not merely random occurrences but are orchestrated by God for a purpose. Through various scriptures, we see that God utilizes grief to test our faith, to draw us closer to Him, and to remind us of our dependency on His grace amidst trials. The knowledge that even our deepest sorrows have a purpose in God's plan can provide comfort and strength during tough times.
