Gain a deeper understanding of the Bible & get closer with God to unlock true peace and happiness

Live the life that God wants you to

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.


This isn’t a program. It’s a path towards permanent change. Let’s walk it together.
