Warrior Testimonies – Read what Called to War is doing to change men’s lives. . .

As a Christian therapist I see men every week who have lost their way due to a false masculinity that abdicates their role as a servant-warrior who loves and protects his wife and children. Called to War is not about macho, but about freedom. Art takes a man through the journey of Gideon from fearfully farmer to mighty warrior. Men can be freed from the very false and often toxic armor we put on for self protection and learn a new openness before God and other men. -Rick Blackmon, Ph.D., Adjunct Faculty, Fuller Theological Seminary

“Core 300 Warrior course has transformed the men in our church. In the first 6 months alone, we doubled our experienced leaders. Plus to my surprise, congregational giving increased by 30% and stayed there, 2 weeks after we started the course.”                                                        – Dr. Gregg Nash, Senior Pastor, Rock Creek Church, Portland

The best part about Core 300 men’s discipleship was seeing how my life has changed afterward. After 12 years of trying to live the Christian life, I recommitted my life and determined to get rid of my selfishness so that God can use me, unhindered. Now, nearly a year later, I’m living a freedom in Christ I’ve never experienced before. I’m not only back in the saddle, I’m watching God work in ways I didn’t even know were possible!- Joel Cheek
The Core 300 men’s Bible study helped grow me through some tremendously difficult trials, and created a band of close Christian brothers who really know me, warts and all. – Al Williams

For 30 years, I had tried with all my heart to follow Jesus, but I kept my head down and tried to avoid conflict of any kind. Especially in the spiritual realm. When pressed, the best I would do is play defense and yield as little ground as possible. Today, I am a Warrior. When I wake up, I awaken to the invisible battle in this fallen world (and sometimes in me) and take it on, offensively. Although I do not win every fight, I have set my face for and found victory as God’s Mighty Warrior! – Mike Gregory



I was given the chance to be a Squad leader for the Core 300, study on Gideon and I am so thankful for the opportunity.

I have learned so much about myself as well as others in my squad. Even though it was originally written for men, I find it even more challenging for me to dig deeper. God has used this study to challenge me in areas of my life that I have been shoving in the back corner of my heart, and also challenged me with my relationship with my boyfriend…we have both grown because of this study.  I have had to make sacrifices, because we are called to be in the world and not of the world. I love it! and love learning how to be a Warrior in the arena!!

-Kaila Shull, Catcher, UCLA Womens Softball, All Pac 10


The Core 300 men’s curriculum is effectively tapping in to what is needed to engage American men in powerful kingdom-focused ways in their families, churches, and communities.  With Gideon as a case study, they use the biblical themes of the warrior to challenge us to “get into the arena” — first by building key interdependent men’s fellowship with other men, then freeing us from the common bonds that tend to drag evangelical men down, and finally by “spurring us on to love and good deeds” in practical ways.  Both the content and the approach are motivating and transforming.–  Steve Adams, Christian Associates, Strategic Partnerships
By leading a table group in the Warrior study, I was able to be open and honest with other men and I quickly became a mentor for the men at my table, providing them encouragement and guidance. As we prayed together and prayed for one another outside the study, it was obvious that God was listening, as the praise reports reflected God’s goodness, mercy and healing!

– Len Krukowski, Squad Leader


This last weekend my Dad and I went away for a time together
and when we ere not surfing or eating, we were learning about Gideon..and how God called him a Mighty Warrior even though he was hiding and alone and afraid. God took away my fears and called me into mens discipleship as his Warrior and I was filled with the Holy Spirit and received a new kind of strength I have never felt before. When the summer is over I can’t wait to go back to school.”

– Jordan, 12
