What does the Bible say about the purpose for suffering?

In 1 Peter 4:17-19, the Apostle Peter emphasizes that judgment begins with the household of God, indicating that suffering is part of God's sovereign plan for His people. The trials we face serve to reveal the genuineness of our faith, much like gold is tested through fire. Furthermore, Scripture reassures us that while we experience suffering, these tribulations ultimately lead to our spiritual maturity and perfection (1 Peter 5:10). God uses suffering not only to purify us but also to strengthen our faith and prepare us for eternal glory, as He molds us into the likeness of Christ.
