I want to personally recommend ChristJitsu to any and all who are seriously desiring to grow in Christ in a consistent, disciplined manner. In addition to the spiritual component of this discipline, the integral relationship with the physical martial art is the best I have ever seen. Being a  Black Belt myself in Tora Ryugi JuJitsu, I can say, without any equivocation, this is the very best combination of a Christ-centered and biblically based approach to the martial arts I have ever read or seen, It is, if you will, the "systematic theology" of Christ-centered and biblically based martial arts. - Justin Alfred, Word in Life Ministries
