David Wilkerson was an Assemblies of God Pentecostal Minister called by God as an Evangelist, Pastor and Prophet. As an Evangelist, David went into the gang-controlled neighborhoods of New York City in the 1950’s and 1960’s winning many gang members to Jesus Christ, the most famous of which is former NYC gang warlord Nicky Cruz. David Wilkerson wrote a book recounting his early days in that ministry titled, The Cross and the Switchblade, which was made into a movie with Actor Pat Boone playing the role of David Wilkerson.
