Peter denies knowing the Lord Jesus Christ not once but three times over. We examine:
We see that even a true believer like Peter can sin seriously - can be overwhelmed by sin and succumb to it. In this case, Peter feared for his life and sinned to save it. Yet Peter’s reaction when he remembered the Word of Christ reveals that he truly was a believer. We gain comfort in knowing that like Peter, we have a Savior who ever lives to intercede for us.
We also look at this event with an eye to God’s sovereignty. God had decreed this event; Christ had prophesied it and Peter, despite knowing the prophecy, still committed the sin. Yet he does not blame God for his sin but recognizes his own responsibility - he sinned because that is what he wanted to do.
