In Totally Christian Karate there are no kicking or punching techniques in the first two levels. We start with avoiding because the art assumes that we are:
1. Old
2.Out of Shape
3. Injured
4. Slow
5. Weak
6. Outnumbered
7. Caught off guard
Ideally none of these is the case. However as a Self-Defense art we must assume they are and train to be effective anyway. Start with avoiding.
An art that cannot be effective under all these conditions might be an effective military combat method or a winning sport method or even an effective brawling method but they are not a Self-Defense Method!
So in Totally Christian Karate we do not go head to head or exchange with the attackers. We make sure everything bad happens to the other guy. Our desire is not the destruction of the attacker but our self preservation or the preservation of someone else because that person is created in the image of God and He loves them.
Scripturally, I never try to pay back wrong for wrong or exchange word for word with others. I think of others more than myself. Remembering all of the times in my life that I may have attacked someone else with my words. I avoid the offense, turn the other cheek and look for the opportunity to share truth with love. This takes practice.
