From My Heart to Yours
I vividly remember what I declared at the altar of a Christian youth camp in Wisconsin back in 1979: "I want to go out and save the world!"
This heartfelt commitment led me to discover my calling as an evangelist, which brought me to Spain in 1987.
As an evangelist, my mission extends beyond sharing the Gospel; my wife Joni and I also teach others how to effectively communicate their faith.
No matter where you are or your level of experience, I am here to help you share the Gospel in creative and impactful wayss

More about Jacob's work
Jacob Bock, an Assemblies of God missionary based in Madrid, Spain. Since 1987, he has dedicated himself to full-time evangelism and training believers to share the Gospel. In 2002, he founded "On The Red Box," a street evangelism ministry that focuses on open-air preaching, particularly in Madrid's Puerta del Sol. This ministry has trained thousands of evangelists across 21 Spanish-speaking countries.
Jacob's approach to evangelism is creative and engaging. He initially used skills like juggling, unicycling, and balloon animal creations to present the Gospel to children. Later, he transitioned to using a red box as a platform for street preaching, which became a trademark of his evangelism efforts.
In addition to his street ministry, Jacob directs the OnTheRedBox School of Evangelism, which has significantly impacted evangelism training in Spanish-speaking countries.
Jacob also shares his experiences and teachings through his YouTube channel, where he provides insights into his ministry and evangelism strategies.

"Jacob helped me a lot to approach people and open my mind."
Â
"I was one of those people who didn't know how to approach people to talk to them about Jesus.Â
Maybe it's because of shame, also because of fear of saying, I don't know how to approach, I just don't know how to do it.
Speaking about my experience with the course that I took with Jacob, helped me a lot to approach people and open my mind."

"I recommend Jacob's books to anyone who wants to know what God expects from them."
Â
"The Do Business With The Mina Book does an amazing job breaking down what each of us as believers want to know. What is God's purpose for my life? What am I called to do? It will take you about an hour to read if you sit down and read it at one time, but it is full of life changing truth about what we are expected to do as believers. How to be faithful. I recommend this book to anyone who wants to know what God expects from them and wants to feel meaningful purpose in their life."
Cristina Wagenaar
"What I felt in my heart was in people on the other side of the world."
Â
"The typical question was how many people were converted and it was somewhat frustrating to say one or two. It was like we had based our success on numbers and I felt in my heart that it was not right to enjoy the truth that I did not enjoy it.
For me it was something extraordinary to be able to understand that what I felt in my heart was in people on the other side of the world who practiced it and enjoyed it."
