How do we know God's sovereignty is true in Peter's denial?

The account of Peter's denial illustrates the sovereignty of God in orchestrating events for the fulfillment of Scripture. Jesus predicted Peter's denial (Matthew 26:34), asserting that this would happen 'so that the Scriptures might be fulfilled.' This highlights God's ultimate control over human actions and events, as seen in Acts 2:23, where Peter acknowledges that Christ's crucifixion occurred according to God's predetermined plan. God's sovereignty assures us that even our failures are used for His glory and fulfillment of His purpose.
