What does the Bible say about the purpose of trials for Christians?

The Bible reveals that every trial faced by believers is not without purpose; rather, they are orchestrated by God for His glory. In John 11:4, Jesus states, 'This sickness is not unto death, but for the glory of God, that the Son of God might be glorified thereby.' This indicates that God uses even the difficult experiences in life, including sickness and hardship, as opportunities to display His glory. Thus, believers can find comfort in knowing that their struggles are not aimless but are designed to bring about a deeper appreciation of Christ’s resurrection and life.
