What does the Bible say about joy after sorrow?

In Isaiah 35:10, we find a beautiful promise that encapsulates the hope of Christians: 'And the ransomed of the Lord shall return and come to Zion with songs and everlasting joy upon their heads. They shall obtain joy and gladness, and sorrow and sighing shall flee away.' This passage reassures believers that despite the pervasive sorrow of life, particularly due to sin and its consequences, there is a future joy that awaits the redeemed. This joy is connected to both present comfort during trials and the ultimate joy of eternal life.
