How do we know that our sorrows will lead to joy?

The assurance that sorrows will culminate in joy for Christians is rooted in the prolific teachings of Scripture. For example, Jesus explicitly states in John 16:20-22 that our sorrow will be turned into joy, affirming a divine purpose in our trials. In addition, Romans 8:28 teaches that God works all things for the good of those who love Him, suggesting that even our deep sorrows serve His plan and bring forth blessings. Furthermore, the witness of Scripture provides historical accounts of God's faithfulness in transforming pain into joy, supporting our hope for the present and future where suffering is eventually erased in the presence of God (Revelation 21:4).
