“When this man writes about evangelism read it because he has field tested it. R. K. has from his first steps in faith gone to the streets with God’s love and power.

In addition he has searched the scripture and the halls of history to discover what God has done and will do.

There is an unfinished mandate from our Lord. It will not be done by theories but by anointed wisdom and face to face compassion. Go with R. K. Castillo on a journey in this book and an adventure into the pages of life."

Pastor Alan Hawkins - New Life CityBram - YWAM Asuncion

"What were you doing when you were 18 years old? I can tell you what I wasn't doing. I wasn't traveling the world as an evangelist preaching to thousands, praying for the sick or seeing God's miraculous hand at work on the planet.

I wasn't living by faith on a missionary training base teaching youth and leading teams into other Countries.

And yet that's exactly what RK Castillo was doing.

RK is a gifted teacher. He brings his wealth of personal experiences, along with the many discoveries he's made over years of dedication to study on these subjects, to us in steps that are easy to follow with words and illustrations that are easy to understand. I've learned so much from him…”
