Start your spiritual journey

Does your spiritual walk feel like a broken puzzle?

“I want deep insights without spending hours studying themselves.”

“I am unsure about complex or controversial topics and want clarity.”

“I struggle to understand the Bible deeply.”

“I want help overcoming doubts, fear, or guilt.”

“I feel isolated and seek community and connection.”

“I need practical application of biblical wisdom for real-life problems.”

“I need clear guidance on how to live out my faith daily.”

You’re not alone. These are the real questions, doubts, and struggles that so many of us carry.

{{Core of the Heart}} is here to walk with you through them.

Hi, I’m {{Johnny chang}}

I’m an ex-gang member turned minister.

After years behind bars and a lifetime of pain, I had a chance encounter with God that changed everything.

I’ve read the Bible over 25 times and spent the last 8 years helping people break free from confusion, guilt, and spiritual numbness.

I created Core of the Heart to fast-track your growth so you don’t spend years stuck in the same place, like I was.

If you stay consistent, I’m confident you’ll experience your first major “unlock” within 30 days.

“I really love Johnny Chang's way of teaching the Bible. He always points to Christ and His sacrifice and resurrection for our eternal reconciliation to the Father in every book of the Bible.”

Christine Hancock

“Johnny’s ministry and teachings has helped me tremendously on my faith journey. I gave my life to Christ late 2024 after coming to the end of myself having realized I could not lead my own life and I needed to Jesus to lead it.”

Jet Yamasaki

“I honestly have no words to describe how Johnny's leadership has helped me grow spiritually. In a world full of noise, full of lies disguised as "truths", Johnny's teachings have literally cured my spiritual blindness.”

Rafael Rodriguez

"I was raised in religion. I was taught fear, rules, and that I had to earn God’s love. But when I heard Johnny preach, everything changed. He didn’t preach religion. He preached Jesus. He made the Gospel simple and clear—that salvation isn’t about what we do, but about what Christ has already done."
