I need to confess something (even knowing that some people who I know and live near, actually read this). I do not read my Bible enough. I do not pray enough. I do not study enough. And I am a poorer man, a poorer Christian, a poorer disciple for it.
The picture of the samurai of old have been blurred by time, distance, and my American cultural bias and influence. I know they were not perfect, and for the most part, not men who followed Christ and his teachings (even after the Portugese missionaries arrived). But, to reuse a bit of scripture from yesterday for an anology: "Finally, brothers, whatever is true, whatever is honorable, whatever is just, whatever is pure, whatever is lovely, whatever is commendable, if there is any excellence, if there is anything worthy of praise, think about these things." (Philippeans 4:8, esv)
The first image that comes to mind of a samurai is the katana, or long sword. We (Americans at least) think of these men as masters of the sword. From a very young age they train to master it. As a Christian what is my sword? The Bible tells me that it is the very Word of God. If I am not in His word, if I am not studying His word, if I am not making His very word a part of me, then I am not learning how to use His word. Not for my own purposes, because if I am truly following Christ than I have laid down my life, but for His purposes and glory.
A samurai lived to serve his lord. He was about his lord's business, and in everything he did, it was an effort to not dishonor his master. I don't know if the Daimyo actually knew his samurai personally, and with them still being human, this is probably not the best example. But my Lord, Christ, desires to know me personally. He wants to spend time with me. How do I get to know my Master? It is done in spending time in prayer, in thinking and meditating about what His word is showing me. About looking around and weighing it against what He has revealed to me.
In my opinion, I am a rather weak 'samurai' in the service the Lord Jesus Christ. But even the weakest samurai was to be of use to his lord to the Daimyo. And I further can benefit in that in my weakness, He is revealed to be strong. But that can only be possible when I yield myself to Him.
Verse for today:
2 Timothy 2:15-19, ESV
Do your best to present yourself to God as one approved,  a worker who has no need to be ashamed, rightly handling the word of truth. But avoid irreverent babble, for it will lead people into more and more ungodliness, and their talk will spread like gangrene. Among them are Hymenaeus and Philetus, who have swerved from the truth, saying that the resurrection has already happened. They are upsetting the faith of some. But God's firm foundation stands, bearing this seal: “The Lord knows those who are his,” and, “Let everyone who names the name of the Lord depart from iniquity.”
Preparing for "battle"
Let us therefore strive to enter that rest, so that no one may fall by the same sort of disobedience. For the word of God is living and active, sharper than any [katana], piercing to the division of soul and of spirit, of joints and of marrow, and discerning the thoughts and intentions of the heart. And no creature is hidden from his sight, but all are naked and exposed to the eyes of him to whom we must give account. (Hebrews 4:11-13, esv - note: actual text uses 'two-edged sword' )
