In Peter’s whole experience — from the shame of his failures through the sweetness of his restoration — we see the mercy of Jesus in its wide range of expression. Peter was mercifully devastated and mercifully restored. It was not the experience of mercy he likely wanted, but it was the mercy he needed. And it was all unfathomably kind, even in its most devastating moments.

As simply worded as the Gospels often seem, the multidimensional Jesus we encounter in them is anything but simple. We can see this in the varied (we might even say extreme) ways Jesus extends mercy.

What likely comes to mind for most of us when we think of Jesus’s mercy are expressions of gentleness. We think of his lamb-like meekness during his unjust trial and his lamb-like sacrificial, substitutionary death on the cross to atone for all our sins. We might think of the Sermon on the Mount, which bursts with a many-faceted mercy (Matthew 5:2–12). Jesus invites us to put away anger (Matthew 5:21–26), to respond to evil with kindness (Matthew 5:38–42), and to love our enemies (Matthew 5:43–48). We might think of the kind of kindness that drew all manner of diseased and disordered people to him for healing (Matthew 8:1–17) and all manner of sinners to him for forgiveness (Matthew 9:10–13).

These are each great mercies in Christ, but they are not the only expressions of his mercy. His mercy wasn’t always gentle. At times his mercy could be devastating. And it’s important we see this because, as the apostle Peter discovered, sometimes the mercy we most need from Jesus comes in a severe package.

Sincerely Self-Deceived

Peter loved Jesus. Jesus knew that. But prior to Jesus’s trial and crucifixion, Peter believed he loved Jesus more than he loved his own life — in other words, more than he actually did. And so Jesus, to prepare Peter for his life’s calling (and even for his death), extended mercy to him — a kind of mercy Peter didn’t expect or recognize as mercy in the moment.

During his final Passover meal with the Twelve, Jesus announced that one of them would betray him. All responded with shock, and eleven with grief (Matthew 26:21–22). They also responded with pride, which was itself a revelation. The news moved each of them to question the others’ loyalty, and to assert himself as the greatest (Luke 22:23–24). Eleven desperately did not want to be that guy, and no one wanted the other guys to think he was that guy.

After mercifully ending that vain debate, Jesus turned to Peter and said, “Simon, Simon, behold, Satan demanded to have you [you all, plural in Greek], that he might sift you [all] like wheat, but I have prayed for you [you, Peter, singular in Greek] that your faith may not fail. And when you [Peter] have turned again, strengthen your brothers” (Luke 22:31–32).

Peter was stunned. Turned again? That implied he was going to turn from Jesus. He was incredulous. Even if everyone else turned away, he absolutely would not (Matthew 26:33). And he said so:

Lord, I am ready to go with you both to prison and to death. (Luke 22:33)

Jesus knew Peter was sincere, but self-deceived. Peter did not know how misplaced his self-confidence was. So, Jesus dropped the bomb: “I tell you, Peter, the rooster will not crow this day, until you deny three times that you know me” (Luke 22:34). To Peter, that just seemed impossible, especially after all they had been through together. So he swore, “I will not deny you,” and so did the others (Mark 14:31).

Mercifully Devastated

And then, in just a matter of hours, after Peter’s sincere vow of loyal love to the death, Jesus’s prophecy came to pass. All it took was a servant girl’s public accusation, and Peter heard himself say the one thing he swore he’d never say: “I do not know him” (Luke 22:57).

After two more denials, the rooster crowed, and Peter was left to face the inescapable, terrible truth: he didn’t love Jesus as he thought he did. When push came to shove, and his own skin might actually be on the line, he had been a coward, and sold out his Lord — the one he knew was “the Christ, the Son of the living God” (Matthew 16:16). It was the worst thing he’d ever done. Likely one of the worst things anyone had ever done. He had failed miserably, sinned immensely, and there was no taking it back.
