What does the Bible say about turning sorrow into joy?

In John 16:20-22, Jesus tells His disciples that they will experience sorrow, particularly as He prepares for His departure. However, He assures them that their sorrow will be turned into joy. This transformation reflects the Christian hope in the resurrection and eternal joy that follows suffering. The woman in childbirth experiences pain but rejoices when the child is born, illustrating how God uses sorrow to bring about new life and joy. This principle applies to believers today, encouraging them to find solace in the knowledge that their trials are temporary and purposeful, ultimately leading to joy.
