You used a clip from a movie where your hero is committing adultery with the kings wife.
That did cause him a bit of trouble didn't it? (Lancelot). And, it wasn't adultery, just a kiss-- but, same idea. I wanted to counter the image of being weak in faith (even though I can barely lift that two-edged, non-sharpened decorative sword). Betrayal of the King was high treason, and he was about to put both of them to death. He made a good point though-- to the queen: that with her will, she chose the king, but her heart chose the knight."
It's a good lesson: If we only love God with our will, but not our whole heart, it's not enough.
The movie, "First Knight," had it's critics, but I liked it. It had a lot of good ideas about the battle between good and evil, and memorable lines like the king to Lancelot: "a man that fears nothing, loves nothing." And the delusional blindness of evil where the evil fallen knight Maligant (also symbolic of fallen lucifer) tells the people to reject "King Arthur's evil god." I don't normally watch war scenes, but, they toned it down quite a bit, even though it is still a violent scene. But, sometimes in this amazing, but crazy world, there are evil dudes that won't change, and war can be necessary. Don't like violence, but, when I watched this a couple years ago, I cheered when Lancelot took out Maligant.
I have watched a few war movies and "Memphis Belle," is an inspiring one where after young and very scared crew had flown safely through all the artillery "flack" blowing apart their plane, and the target (a factory, not a city at least), was clouded over, they cheered because they thought they were going home. But, the Captain turned the plane around, and said that they were sent to stop a factory from producing weapons (destroy it), and, "if we don't do it, someone else will have to come and risk their lives to do it."
Others are more difficult to sit through. I don't know why I stayed, but, I wept all the way through a more recent war movie that showed the horrors of modern combat.
Same concept in the movie, "The Wrath of Khan," (Star Trek II). All the guy did was go around killing people and destroying things, and, in the end, he symbolically represented the devil, and Captain Kirk defeated him.
In real history, Jesus defeated the devil, from the first confrontation with that face of evil in the desert, using the Word of God as a sword, to the last, in the Garden of Gethsemane and Roman execution/crucifixion, allowing the powers of evil to think they were killing Him, when in their crazed and blinded delusions, they defeated themselves by their own hand.
Jesus also knew that in this world, the meek must be defended and protected, until we all inherit the earth, sooner than later, and He made a point of commending virtuous Roman officers and commanders, and even made a reference to kings planning a war, but suggested they try to mediate disputes, and warned that those who take up the sword, or maybe He meant, those who rely on the sword alone for defense against evil threats, or who are not authorized to use deadly force, or who use weapons for evil purposes, such as Islamic militants, or those who use weapons against innocent citizens, "will be defeated by the sword. When it comes to spiritual warfare, though, He said that Christians would be given words that can not be defeated, or the sword of truth. I believe this applies to other areas besides the written word, such as "all things work together for good, for those who love God, and are called according to His purpose." (Romans 8:28).
