Run Baby Run
In 60 seconds
Nicky Cruz grew up in a Puerto Rican home soaked in spiritism and violence, then ran Brooklyn's most feared gang, the Mau Maus. A skinny country preacher named David Wilkerson kept walking into his territory until hate ran out of fuel. One night Nicky broke down at an altar, gave his life to Jesus, and walked back to the hangout to tell his gang he was done. He went from mopping floors in Teen Challenge to founding Nicky Cruz Outreach, preaching worldwide that if God can change him, He can change anybody.
Before you start
Why it matters
This is the original street-level conversion story that launched a thousand ministries — raw, violent, and honest about how hard change actually is. Read it if you love true redemption stories, work with troubled kids, or secretly believe some people are beyond saving. Cruz proves otherwise with his own scarred body.
14 ideas, in the book's order
The big ideas
- 1Chapter 1
A Mother Who Summoned Spirits and a Boy Who Ran
Nicky Cruz's childhood in Puerto Rico was ruled by the occult. His mother was a medium who summoned spirits; the home was filled with occult practice. His father was violent and alcoholic. His mother told him she wished he had never been born and called him 'son of Satan.' Nicky slapped her across the face, knocking her down, then ran from the house knowing he had committed an unforgivable act. At age 15 he was sent to New York to live with his brother.
The idea
Cruz opens with the wound, not the gang.
Try this: Write down the one sentence from your childhood you still hear when you're at your lowest — then decide out loud whether you'll keep letting it speak.
- 2Chapter 2
President of the Mau Maus
Nicky arrived in Brooklyn speaking almost no English and was mocked as a Puerto Rican immigrant. He joined the Mau Maus, a Brooklyn gang based along Myrtle Avenue. Their rivals included the Chaplains and the Bishops. He rose to become the gang's president (warlord), known for carrying zip guns, switchblades, and chains. Gang life centered on rumbles, drugs, stealing, and fighting. He was arrested many times as a teenager and spent time in juvenile detention.
The idea
The gang gave Nicky what home never did: identity, protection, and a title.
Try this: Identify one group in your life that accepts you unconditionally — then ask honestly whether it's pulling you toward or away from who you want to be.
- 3Chapters 2-3
Knifed in a Rumble and Feeling Nothing
In a rumble with a rival gang, Nicky was knifed and beaten. He survived. He felt no pain at the moment, only rage. The scar remained as a badge of honor.
The idea
A body so armored by anger it doesn't register being cut.
Try this: Notice one hurt you've stopped feeling because you turned it into anger — name it to someone this week before it scars over completely.
- 4Chapters 3-4
The Preacher He Slapped and Spat On
David Wilkerson, a skinny country preacher from Pennsylvania, came to New York to preach to gang members after reading about a gang trial in Life magazine and feeling God's call. Nicky first saw him at a street meeting, spat in his face, slapped him, and threatened to kill him. Wilkerson told Nicky, 'You can kill me, but you can't kill Jesus Christ.' Nicky ordered the Mau Maus to disrupt his meetings. Wilkerson kept coming back despite Nicky ordering the Mau Maus to disrupt his meetings.
The idea
Every instinct Nicky had said a man who won't fight back is weak.
Try this: Pick one person who has written you off and show up for them once more this week — no argument, just presence.
- 5Chapters 4 and 6
The Arena Riot That Never Happened
Wilkerson arranged a large evangelistic meeting at St. Nicholas Arena in Manhattan. Nicky planned to disrupt it and beat Wilkerson in front of everyone, bringing Mau Maus with him. Wilkerson challenged Nicky to bring his gang, promising he could come on stage and say anything he wanted. Nicky went on stage. He found himself unable to speak his planned curses. The meeting ended without the riot he expected.
The idea
The most violent man in Brooklyn was defeated not by security or scripture but by his own tongue refusing to cooperate.
Try this: Before your next confrontation, write down exactly what you plan to say — then ask whether any of it is actually true.
- 6Chapter 7
Alone in the Lions' Den with a Bible
Nicky sent word that if Wilkerson ever came into Mau Mau territory alone he would be killed. Wilkerson responded by walking into the gang's hangout alone, carrying only a Bible. Nicky slapped him and knocked him down. Wilkerson got up, said he would not fight back, and told Nicky he loved him — 'Nicky, you can cut me up, but I still love you.' Nicky was shaken. No one had ever shown him such unconditional love.
The idea
This is the hinge of the whole book.
Try this: Say the words 'I love you and I'm not leaving' to one person who least deserves to hear it from you.
- 7Chapters 8-9
Dreams, Emptiness, and an Altar Call
Nicky began having dreams and could not sleep. His violence and drug use continued but he felt increasingly empty and haunted. He finally went to Wilkerson and told him he wanted to change. At a meeting, under conviction, he went forward during the altar call. Wilkerson prayed with him, and Nicky gave his life to Jesus Christ, weeping as he confessed his sins and cried out, 'Jesus, help me! Save me, Jesus!'
The idea
Notice the sequence: nothing external changed first.
Try this: Stop performing for one night: name the thing that keeps you up at 3 a.m. to God or to a friend, out loud, tonight.
- 8Chapters 8 and 10
Telling the Gang He Was Done
The night of his conversion, Nicky returned to the gang's hangout and told the Mau Maus he was through with crime and drugs and had found Jesus. Many members mocked him. But they did not attack him.
The idea
Quitting a gang is supposed to cost you your teeth.
Try this: Announce one change to the friends most likely to laugh at it — within 24 hours of deciding, before you talk yourself out of it.
- 9Chapters 9 and 11
The First Test: Hands at His Side
Nicky's first test after conversion came when gang members came to beat him. He did not fight back. Instead he told them about Jesus, which stunned them. He gave up drugs and crime, began reading the Bible and praying — specifically asking God to help him control his violent temper — and started preaching on the streets to his former friends.
The idea
For a warlord, standing still while fists swing is harder than any rumble.
Try this: Choose your most reliable anger trigger this week and pre-decide one different response — then actually do it when it hits.
- 10Chapters 10 and 13
Mopping Floors for the Ministry
Nicky began working with Wilkerson's Teen Challenge ministry in Brooklyn, helping drug addicts and gang members. His first assignment was mopping floors and cleaning toilets. He preached in churches and on the streets about what God had done for him, returning to his old neighborhood to tell gang members about his conversion, despite threats from his old gang.
The idea
The president of the Mau Maus starts his second life with a mop.
Try this: Volunteer for the least glamorous task at your church, shelter, or community group this week — and do it without telling anyone why.
- 11Chapter 11
Gloria
Nicky met Gloria, a young woman who became his wife. Gloria supported his ministry, her patience and prayer helping him overcome his violent temper. They later had children.
The idea
The book doesn't pretend conversion fixed everything overnight.
Try this: Thank the person who has been most patient with your worst trait — name the trait out loud when you do it.
- 12Chapter 12
Out on His Own: Nicky Cruz Outreach
Nicky felt called to start his own ministry, distinct from Teen Challenge, to reach street kids, gang members, and drug addicts. He and Gloria founded Nicky Cruz Outreach. He preached across the country and internationally, telling his story of transformation from gang leader to evangelist and seeing thousands of young people respond.
The idea
The apprentice becomes the founder.
Try this: Mentor one young person who's heading somewhere bad — one hour, this month, starting this week.
- 13Chapters 13, 15, and 18
Going Home to Puerto Rico
Nicky returned to Puerto Rico to visit his parents after years away. His mother had become a Christian. Their reunion brought healing; Nicky forgave his parents for the abuse of his childhood, and his father also came to faith. The family was reconciled.
The idea
The book's full circle closes here.
Try this: If there's a family rupture you've labeled permanent, make one contact this week — a call, a letter, a visit — and see what God does with it.
- 14Chapters 15, 25, 27, and the Epilogue
If God Can Change Him, He Can Change Anybody
The book closes with Nicky reflecting on how God took a gang leader and made him an evangelist. He describes learning to rely on the Holy Spirit's power in his ministry, praying for the sick and seeing dramatic conversions among gang members and addicts. He continues leading Nicky Cruz Outreach and preaching worldwide, expressing his vision to continue reaching the lost with the message of Jesus Christ. His life is a testament that with God nothing is impossible, and that if God can change him, He can change anybody.
The idea
The closing claim isn't sentiment; it's an argument built from the evidence of the preceding chapters.
Try this: Name the one person you've privately written off as hopeless — and pray for them by name every day this week.
Worth remembering
Best lines
“You can kill me, but you can't kill Jesus Christ.”
“Nicky, you can cut me up, but I still love you.”
“Jesus, help me! Save me, Jesus!”
“son of Satan.”
A fair critique
Where it falls short
The book is a conversion narrative from 1968, so it moves at the speed of testimony rather than journalism — dialogue is reconstructed from memory decades later, and the spiritual interpretation of every event leaves little room for psychological or sociological explanation. Gang life is rendered vividly but briefly; readers wanting a deep history of the Mau Maus or New York's gang era will need other sources. The miracles are presented as Cruz reports them, taken on faith rather than examined. None of this dulls the story, but skeptical readers should know the genre going in.
In one sentence
If God can change the man who spat in a preacher's face and ran Brooklyn's meanest gang, He can change anybody — including you.
Is it for you?
Who should read it
Anyone who loves a true redemption story with real scars, and anyone working with gang members, addicts, or kids the world has written off. Also essential for readers who secretly believe some people are beyond God's reach.
