How do we know that suffering is a gift?

In 2 Corinthians 12:7-10, Paul explicitly states that the thorn in his flesh was given to him to prevent pride and to highlight God's grace. It is through suffering that we are reminded of our limitations and are brought to the throne of grace, as we see in Hebrews 4:16. The suffering that we endure draws us into deeper reliance on Christ, showing us that His strength is made perfect in our weakness, which ultimately serves to glorify Him and strengthens our faith. Thus, suffering, while painful, can be recognized as a transformative gift from God.
