God has a way of taking our moments of deepest confusion and doubt and using them to strengthen our trust and dependence on Him. He takes our seeds of faith and turns them into a tower of conviction and confidence. When we are most perplexed, He is most in control. When we are weakest, He is strongest. When we need Him, He is always there.

David Wilkerson, my friend and mentor, is a living testament to this truth. More than any man I know, he trusts God implicitly. He never allows confusion or doubt or other people to steer his decisions. Every worry, every question, every moment of concern is placed at the feet of Jesus until he hears an answer. He listens to God and God alone. That is why God has used him so mightily in his life and ministry.

David Wilkerson was just a country preacher from Pennsylvania when God told him to go to New York and reach out to the gangs. He had been watching a news program that discussed the gang problem in the inner city when God spoke to his spirit and told him to go. No one could imagine this skinny preacher being able to reach such a hardened group, yet he obeyed and went.

I’ll never forget his boldness in the face of danger. We cursed at him, humiliated him, screamed in his face, yet he kept coming back. I would never have stepped foot into a church building had I not been so fascinated by his guts, his complete disregard for his own safety. What would make a man do such a thing? What kind of God would give a man such confidence, such trust, such gumption that he could walk into the middle of hell and stare down the devil himself? What would make a scrawny street preacher think he could come onto our turf and tell us what to believe?

I had to know, so I went to his service at St. Nicolas Arena. In front of hundreds of strangers and dozens of my fellow gang members, I fell to my knees before the altar and surrendered to Jesus. I cried out for Him to save me, and He did. I gave up trying to do it on my own. I looked at David Wilkerson, at the love in his eyes, at the peace in his spirit, at the courage in his heart, and I knew that I wanted what he had. This was a God I could worship. This was a Jesus I could relate to.

Nicky Cruz, internationally known evangelist and prolific author, turned to Jesus Christ from a life of violence and crime after meeting David Wilkerson in New York City in 1958. The story of his dramatic conversion was told first in The Cross and the Switchblade by David Wilkerson and then later in his own best-selling book Run, Baby, Run.
