From Hagakure - The Book of the Samurai

Hagakure means "hidden by the leaves" or "hidden leaves". It's a collection of writings or a philosophy if you will by the Samurai Yamamoto Tsunetomo. He never saw actual warfare and after the death of his daimyō (master - a great feudal leader - leading figure of a clan - literally means "great name") he was unable to commit the ritual form of suicide following the death of one's master, called junshi, because it was outlawed by his Lord (daimyō). He then became a Buddhist monk and lived out his days writing in near seclusion.

From the Hagakure-

Every morning one should first do reverence to his master and parents and then to his patron deities and guardian Buddhas. If he will only make his master first in importance, his parents will rejoice and the gods and Buddhas will give their assent. For a warrior there is nothing other than thinking of his master. If one creates this resolution within himself, he will always be mindful of the master's person and will not depart from him even for a moment.

Moreover, a woman should consider her husband first, just as he considers his master first.

Pretty interesting in it's own right huh? Now what if we applied a little poetic license and some of that samurai determination and it read a little something like this ...

Every morning one should first do reverence to the Lord and then to others. If he will only make the Lord first in importance, others will give their assent. For a warrior there is nothing other than thinking of the Lord. If one creates this resolution within himself, he will always be mindful of the Lord's person and will not depart from Him even for a moment.

Sounds simple but the message is deep. Very deep. A disciplined life for the Warrior and a determination to always meditate on the Lord keeps us loyal and obedient.

Another --

Being a retainer is nothing other than being a supporter of one's lord, entrusting matters of good and evil to him, and renouncing self interest. If there are but two or three men of this type, the fief will be secure.

If one looks at the world when affairs are going smoothly, there are many who go about putting in their appearance, being useful by their wisdom, discriminations, and artfulness. However, if the lord should retire or go into seclusion, there are many who will quickly turn their backs on him and ingratiate themselves to the man of the day. Such a thing is unpleasant even to think about. Men of high position, low position, deep wisdom and artfulness all feel that they are the ones working righteously, but when it comes to the point of throwing away one's life for his lord, will get weak in the knees. This is rather disgraceful. The fact that a useless person often becomes a matchless warrior at such times is because he has already given up his life and has become one with his lord. ...

Loyalty is said to be important in the pledge between lord and retainer. Though it may seem unattainable, it is right before your eyes. If you once set yourself to it, you will become a superb retainer at that very moment.

Applicable to the modern Christian Warrior? I think so ...
