“Women, buy this book for the men you love! Called to War will most assuredly be compared with Wild at Heart, Healing the Masculine Soul and Raising a Modern Day Knight. Men-of-God, saddle up; you have been Called to War!’  – Marc Stein, Vice President,   Joni and Friends

“This is not a marriage book, it is a man’s book, yet many of the wives of men in our Warrior class were telling me how years praying for their husband had been answered” -Wes Harding, Executive Pastor at The Bridge of South Bay

Called to War will become one of the other well-worn books in your library.  Art has tapped into the true spirit of a man’s soul. A ‘how-to’ spiritual manual and a self-help and small group workbook that instructs on what robs men of their hidden power in Christ.  Want to be all you can be??  Get this book!” -Jason Bracero

“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

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

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, Squad Leader

I was a Christian that believed he should be instructing men, not taking a course for men. I believed my walk with God was strong, my marriage was solid, and that as a man I pretty much had it all together. But then I encountered the Core 300 Warrior mens discipleship training. The men’s study asked me to look deeper; past the surface to realize who I had become and what I was lacking in my walk with God. In my men’s group were men like me. Together we grew and became more self-less. And, with the guidance of the Core 300 leadership, we began to more fully understand the needs of others and have again become servants. For some, the series reminded us again what it means to walk in the essentials of servant leadership, for others, the series taught us how. – Dave Tofanelli
It is amazing what being a part of the Core 300 men’s ministry has done to change my and the other men’s life. Learning to wear the Armor of God sets you apart and prepares you take on the curve balls life throws at you. The armor protects us from the anger, lust, jealousy, and greed that can control your life. One of the best parts of being in the Core 300 is sharing the story of the coin with other men who have not experienced being a part of the Core and seeing their desire to become a Warrior, Priest, and King.

– David Lippman

For me, prior to the Core 300 men’s study, I found myself on the edge of the arena. I knew I wasn’t simply sitting in stands, but on the other hand, I wasn’t in the center of arena, fully engaged in God’s battle either. I wasn’t working together with other men in a small group. Discipleship was misunderstood. Men, bonding in trust, and seeking the protection that comes when a men’s small group loves and defends one another, was a wonderful experience that has changed me forever.

As a result of the Warrior training, the personal bondage to porn, a failing marriage, and other personal failures in my life are being defused. I can now say that I am engaged with other men, in the core of God’s army as he uses me and my fellow Warriors to accomplish His will! – Len

Upon graduation from the Warriors men’s study, I was presented with a majestic coin that I carry in my wallet. This coin reminds me daily to put on the Armor of God and be prepared to face each day. What Art and his team gave me in this men’s study was a delightful insight to myself. The courses were not easy and in fact I had several classes where the subjects were downright uncomfortable. I therefore have learned to be a Warrior, a Priest and a King. All were brought to me as challenges to undertake and conquer. This men’s ministry is an experience that can change each men’s life and make him an overcomer.

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!!

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 men’s 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.”
