I don't want you to read my mind- I want you to read your BIBLE. Prayer, word, sacrament, good deeds- these are the pursuit of righteousness.
I have read the Bible, numerous times, but you're the one posting here so you're just making excuses if you won't say what you mean.
If God commands us to go to war (as He once did), then of course it is the legitimate use for violent force. Likewise if He sees fit to destroy Pharaoh's army- that's His work (not ours).
But Jesus nowhere gives His apostles or disciples the commandment to use weapons, make war, use violence for entertainment or even physical training. Not once. OTOH, he asks us to be gentile as lambs, and to turn the other cheek. He wants us to be *different* from the world and its standards. I know that sounds hard for people who love to feast their eyes on violence and fighting for entertainment, but you have to stand apart from the world, not blend in and try to give worldliness a Christian spin or flavor.
Saying Jesus never gave a commandment to physically train does not equate to it being sinful. Most forms of entertainment people participate in are never addressed by Jesus, that doesn't mean they are sinful. Jesus never tells his disciples to go scuba diving. Are scuba divers sinners?
And you talk about reading the Bible but you are confused yourself about what it says. There is no where that says "gentile as lambs" or "gentle as sheep". I can guess that you are maybe referring to Matthew 10, so maybe you should go read it again.
Turning the other cheek has nothing to do with sports or violence. Jesus gives other examples to illustrate the point he is making, such as if someone sues you, if you are forced to go a mile, or if someone wants to borrow from you. None of those have anything to do with sports or violence or pacifism. Even the turning of the cheek has nothing to do with physical violence. You can read any commentary about the verse and they talk about the slap being an attack on someone's dignity or honor, not a physical assault.
Perhaps you should go take your own advice on reading the Bible because every time you reference something in it the context is completely irrelevant.
I once saw a Christian MMA fighter thank God for his victory in the octagon. I considered it one of the least Christian things I had ever seen, not to mention the confused, mixed-up message that it sends. "I punched a guy and kicked him and tried to hurt him enough to make him submit to defeat for entertainment and personal glory- now I'll thank Jesus for that". Beating up someone for Jesus. Seriously? How idiotic and carnal- and unChristian. Stunning hypocrisy, actually.
Most of life involves someone winning and someone losing. Two football teams play and one wins. Many candidates interview for a job, one is hire. You date multiple people but you only marry one. Several companies bid on a contract and only one is chosen. Many pets at a shelter need a home but you only adopt one. You inventing someone else's motives is just revealing of your own insecurities. You don't have the ability to perform well at a sport and so you automatically accuse others who do of doing so for "personal glory".
And again you're straw-manning with claiming people are getting "beat up". Sometimes injuries happen, but they are rare. I train with dozens of people and we go to competitions, some win, some lose, we're sore for a day, and then we go back to training and having fun. Professionals train every day, multiple sessions a day, how can they do that if they're getting beat up? The fact that you keep using the same silly argument you can't prove just shows how sad your argument is.
If Christianity is too peaceful or pacifist for you- then try Islam. You get to kill, fight, oppress, you don't have to change your heart, you can keep your worldliness, idolize strength, submission and personal glory, and you still get to pretend you're serving God. You can be carnal and violent and fit right in.
Jesus didn't beat up on people for personal glory, money or victory, nor did His Apostles. I say yes to what Jesus says yes to, and no to what He says no to. That's the beginning of the pursuit of righteousness.
There's lots of things Jesus never did. Jesus never posted on internet forums yet I see you right here. If "Jesus never did it so it's wrong" is your argument then you aren't even being consistent with your own arguments. Why should anyone take you seriously?
