How do we know God controls our ability to stand firm in faith?

The narrative of Peter's denial illustrates that God sovereignly orchestrated events to reveal Peter's true nature and inability to remain steadfast on his own. Jesus prophesies Peter's denial to emphasize human helplessness and divine sovereignty. In John 10:28-29, we see that no one can snatch the Lord's sheep from His hand, underscoring that God keeps His own and imparts the grace necessary to stand firm in faith. This assurance is crucial for believers to acknowledge: our ultimate strength lies not within us, but in God's enduring faithfulness.
