The Power That Changes Lives
In 1958, a young country preacher named David Wilkerson walked into the gang-infested streets of New York carrying little more than a Bible and a burden from God. His book The Cross and the Switchblade (later adapted into a 1970 film) tells the story of gang members, heroin addicts, and young people whose lives were transformed through the power of God.
As I read the book, I found myself moved to tears again and again—not simply because addicts recovered or criminals changed direction, but because of the undeniable presence of something greater than human effort. The stories revealed the life-changing power of the Holy Spirit—also called the Holy Ghost—actively working in human hearts.
Who is the Holy Spirit? Where does He come from? What does He do? And why is His role still so important today?
The Holy Spirit is not merely a force, emotion, or mystical energy. According to Scripture, the Holy Spirit is the Spirit of God Himself—fully divine and active in the world.
From the opening pages of Scripture, God's Spirit is present. The Holy Spirit is part of the Trinity: Father, Son, and Holy Spirit. Jesus spoke clearly about Him before His crucifixion, “But the Helper, the Holy Spirit, whom the Father will send in My name, He will teach you all things...” — John 14:26
The Holy Spirit is personal. He teaches, comforts, convicts, guides, and empowers believers.
One area of confusion for many Christians involves Pentecost. Did the Holy Spirit come only upon the apostles, or upon believers generally?
As I dug a little deeper, I discovered something I found fascinating. To Jews, Shavuot, or the Feast of Weeks, was celebrated fifty days after Passover (see Leviticus 23:15–16).
The Greek word Pentecost simply means fiftieth. To Christians, Pentecost marks the coming of the Holy Spirit fifty days after Christ’s resurrection (Acts 2).
What surprised me was that Christ’s followers were already gathered for an existing Jewish feast when Acts tells us, “And they were all filled with the Holy Spirit...” — Acts 2:4.
So, what began as a Jewish celebration unexpectedly became the setting for what many view as the birth of the Christian Church because, from that moment forward, God’s Spirit would dwell within believers through Christ.
As I reflected on that verse in 1 Corinthians 6:19 I found myself pausing. If believers truly become dwelling places for the Holy Spirit, then our physical bodies essentially become temples. I had to ask myself: How do I treat my temple? It is a sobering thought.
After all, numerous Bible-based diet and wellness programs have emerged over the years stressing the importance of respecting what we put into—or do to—our temple. The idea reaches beyond food. It also causes us to think about our habits, choices, and how we care for the bodies we have been given.
Jesus said, “And when He (the Holy Spirit) has come, He will convict the world of sin, and of righteousness, and of judgement.” — John 16:8
In The Cross and the Switchblade, hardened gang members openly wept and surrendered their lives to Christ. This was more than emotional hype. It was conviction. And it did not stop with a handful of people. Thousands of teenagers eventually came through Teen Challenge ministries and experienced transformed lives.
Of course, feelings alone can be confusing, especially during difficult seasons of life.
Scripture remains the standard many Christians use to better understand what is happening in their lives.
David Wilkerson came from a Pentecostal background. Mentioning his ministry is not an endorsement of one denomination over another. As a former Catholic who became Baptist decades ago, I understand that denominations sometimes differ widely in interpretation and practice.
If you are moved to know more about this subject, consider visiting a Bible-believing church that encourages questions and helps strengthen your personal relationship with Christ.
As Teen Challenge expanded beyond New York into cities across America—and eventually around the world—it even reached places like Los Angeles.
What surprised me was learning that the work never really stopped.
Despite the best efforts of countless outreach programs and prevention initiatives, states like New Mexico and California continue to face widespread and heartbreaking struggles with addiction.
The need for hope and transformation is still very real. I truly believe that no one is too far from the love, grace, and power of God, and I’m not alone.
