Christianity and martial arts, is there a conflict?

Boy we could write a book on this one. Once we have settled that there is no conflict in a Christian practicing self defense (King David was a warrior), we must then come to grips with another aspect of martial arts practice. Since this forum carries the heading of "Internal Arts" lets address the issue of ki or chi. Little consideration need be paid to the subject if you practice a modern or so called "reality based system”. But if you are involved in a traditional system as I am the chance of having to deal with the subject increases greatly. On this topic I can only render my opinion. The existence of chi has not been conclusively and scientifically proven. However I cannot dismiss the possibility of its existence, If it does exist I see two ways to deal with it. If it is a spiritual force that must be developed through any number of eastern meditative practices I have no desire to get involved with it. My understanding of spiritual matters is grounded in my faith and Jesus never discussed the subject. If on the other hand it is the electrical charges that travel our neurological system to spark movement in the muscles and the rest of our system, then we are dealing with something that is a part of the physical being that we were created as. In this case eastern practices are not required.
I tend to be comfortable with the latter explanation and so development is possible without an understanding of oriental philosophy. It is possible that the word chi or ki is simply an ancient concept to explain a natural occurrence. Let me give an example of this oriental way of teaching and explaining a concept. We often stress sinking the elbows and striking by driving the punch with the elbow. We also talk of the elbows being heavy and the energy being in the elbow. This language is an excellent way to focus our attention to a certain concept in as few words as possible. We know that the elbow is a joint and so it cannot drive a punch or be heavy or sink on its own. But by focusing on the elbow we will naturally be required to lower the shoulders by activating the latisimus dorsi. Driving the punch with the elbow requires contraction of the front deltoid as the lats maintain the proper tension. The pectoral muscles are also engaged to bring the elbow in as it travels forward driving the fist ahead of it. By focusing on the elbow the correct muscle groups can be utilized. So while the idea of elbow energy sounds wonderfully mysterious, it in fact is a very simple and practical way to help us focus our attention on the proper mechanics of a technique.
Over a lifetime of practice, focusing on proper posture, mechanics and relaxation, incredible power can be achieved. Years of practice can lead to complete relaxation of all muscles not involved in execution of the technique. This allows for increased speed as well as proper follow through. The muscles that act as a brake in beginners are not engaged in the advanced practitioner. Proper posture allows support of the technique to be structural instead of muscular which promotes greater relaxation. The goal is to have the technique originate by pressing the foot against the ground which creates the driving force. Once the technique or strike makes contact it is supported by proper posture and the reaction force is focused back to the ground. If you add to these concepts proper mental focus, a synergistic effect can be achieved. The result is greater than the sum of the individual parts. Striking appears nearly effortless.
The above treatment of the subject allows me to continue to develop what God has given me without compromising my faith. I would enjoy hearing from others on this subject.
