In 1958, Pentecostal pastor David Wilkerson of Assemblies of God is touched by an article in Life about seven teenagers who are members of a criminal gang. Alone and with little money, he goes to Brooklyn, sometimes at the risk of his life, to talk about Jesus with members of street gangs. There, Wilkerson met Nicky Cruz, a member of the "Mau Maus" street gang.

The book became a bestseller, with more than 15 million copies distributed in over 30 languages. 

A profoundly moving and beautiful book. David Wilkerson was a sheltered country pastor with a charismatic background who was called by God to minister to troubled inner-city youth, who were often violent and addicted to drugs.
