What does the Bible say about the cause behind suffering?

In Scripture, suffering is not without purpose; rather, it often serves to reveal God's sovereignty and purpose. Job's trials are a prime example of this, as his friends mistakenly assumed his suffering was due to hidden sin. However, God allowed Job to suffer without a cause to demonstrate His power and the genuineness of Job's faith, ultimately showing that God's plans surpass human understanding. Similarly, David's confrontation with Goliath illustrates how God orchestrates events for His glory and the good of His people, reminding us that there is indeed a cause behind all occurrences in life.
