How does the story of Peter's fishing illustrate God's sovereign grace?

The account where Peter, after toiling all night without catching anything, reluctantly obeyed Jesus's command to cast his net once more is a clear illustration of God's sovereign grace in action. In Luke 5:4-6, after Peter lets his net down at Jesus's word, he catches a miraculous number of fish, demonstrating the power and authority of Christ. This event symbolizes how God intervenes in the lives of sinners, turning our futility into abundance when we yield to His will. It emphasizes that salvation comes not from our efforts but from His divine purpose and grace.
