What does the Bible say about enduring trials?

Scripture emphasizes that trials and afflictions serve a significant purpose in the life of a believer. James 1:2-4 encourages us to count it all joy when we face various trials, as they test our faith and produce perseverance. This testing leads to spiritual maturity, a key theme in biblical teaching. Additionally, in John 15:2, it is highlighted that every branch that bears fruit is pruned to bear even more fruit, which underlines the necessity of trials for spiritual growth and refinement.
