How do we know that suffering leads to growth in faith?

The Scripture teaches that suffering plays a critical role in a believer's spiritual maturation. According to 1 Peter 1:6-7, the trial of our faith is more precious than gold, as it is refined and proven through fiery trials. This process leads to the cultivation of endurance, which enables believers to withstand future trials with greater faith. Furthermore, when believers endure suffering, they come to realize the sufficiency of God's grace and their own weakness, which ultimately proves that their faith is not self-derived but divinely provided. This assurance glorifies God and confirms their standing as His children.
