Although Peter declared that he would lay down his life for Jesus, when he was questioned by a servant girl, he denied Him three times. Rather than view Peter’s actions with judgment, Alistair Begg explains that Peter’s failure serves as a warning to all believers. The seeds of every sin are latent in our own hearts—and, like Peter, if we trust in our own strength, we will fall. The life of faith cannot be built on our promises to Christ but must be fixed on the promises He makes to us.
