As I mull over Jesus’ death and resurrection this Good Friday, I’ve been thinking about Peter’s transformation. I would put the change in his life up against Paul’s for scale of impact of the gospel.

Peter is the kind of guy who thinks out loud, who says what everyone else is thinking. He acts first and thinks later. He’s an uneducated fisherman who learned his trade from his father. For me, the following events sum up his nature.

When he sees Jesus walking on water, he makes the jump of logic that if Jesus can defy rules of nature, he should be able to as well. What incredible, uninformed passion he shows as he climbs out of the boat and tests the surface tension of the undulating waters! It’s amazing to me that, in front of the eleven disciples who never left the boat, Jesus remarks on his lack of faith.

No other chapter sums up Peter’s complexity better than Matthew 16. When Jesus asks who the disciples believe he is, Peter declares his conviction that Jesus is the Messiah and the son of God. It’s on this confession that Jesus will build his church. Yet, a few verses later, Peter reprimands Jesus for talking about his upcoming death, and Jesus puts him in his place: “Get behind me, Satan.” Now, that’s a rebuke! I picture Peter like a dog. When he goes in the wrong direction, you give him a smack or yank on his leash. He sits there stunned for a minute, then shakes it off and sets off again in a different direction. He doesn’t take rebukes personally.

John 13 shows that he’s a long way from getting it. He refuses to let Jesus do such a menial job as wash his feet. Then he pledges loyalty, denying that he would ever deny Jesus. Couple this with his swordwork at the olive grove a few chapters later, and you begin to see that it’s an issue of expectations. I think Peter believes Jesus is preparing to lead an earthly insurrection. Servanthood, arrest and death don’t fit his view of Jesus’ destiny and goals.

Then there’s the lowpoint. While the other disciples flee, Peter sticks around and follows from a distance, only to try to protect himself from the same fate by distancing himself and then flatly lying about his connections to Jesus. His anguish over his denial turns to flight. He heads back home to comfort, the life that comes naturally to him, trying to move on from his failure. He goes back to fishing.

So, when Jesus steps out of the picture, his successor is not at all ready. Is this really the man you want to turn the church over to? Jesus puts a lot of stock in the fact that Peter will rebound from the harsh lessons he learned out of betraying his rabbi and disappointing himself. Jesus turns Peter’s focus from a spiral of dispair with a brief and direct conversation on the beach. Then he’s gone, and Peter is on his own.

Along comes Acts, and Peter is a different man. His hotheaded, impulsive, speak-first ways have morphed into a boldness with a lot of maturity. Maybe you could call the upper room his coccoon. The first words from Peter include a number of quotes from Scripture. I believe he spent the silent days after Jesus left, immersing himself in the Scriptures and in prayer — the qualities the apostles will become known for.

From there, we see a Peter in full command of himself and his followers. He preaches to thousands. He looks lame beggars in the eye and heals them. He faces down Pharisees and Jewish leaders, who can only marvel at his transformation, noting only that he had been with Jesus. Sure, he does some things wrong. I think some of his early decisions are a bit suspect, and Paul later calls him on some hypocrisy. But no one can deny Acts portrays a different Peter than the gospels depicted.

In Leading With a Limp, Dan Allender says that a leader cannot have true humility without being humiliated. And he can’t be truly successful without acknowledging his brokenness. Peter became the leader of the early church because he went through such a deep valley. He came out motivated, compelled by grace and love to follow this Jesus who had done so much for such an undeserving failure.

That’s what Easter is all about.
