That`s a very complex question , you see regularly somebody would say yes it is strictly a sin.but when you think about it what about when your are fighting for a whole nation to be out of harms way.what about when your protecting something you believe in or what about when you are saving people.is it still a sin.religiously speaking 'never do something bad to do some thing good , it`s still a sin'. ex:if you kill a terrorist so he wont kill dozens of innocent peoplel.is that a sin? ruth is this question would most likel be answered based on the persons opinion...i think its a sin if it doesn`t have a good cause

This is a very serious question and we need to reason on it. Is it not true that God allowed ancient Israel to engage in warfare? God directed ancient Israel to use warfare to take possession of the land that he himself designated as their inheritance and to execute people whose depraved practices and defiance of the true God caused Jehovah to view them as being no longer fit to live. ( see Deut. 7:1, 2, 5; 9:5; Lev. 18:24, 25) Nevertheless, mercy was shown to Rahab and to the Gibeonites because they demonstrated faith in Jehovah God. See (Josh. 2:9-13; 9:24-27) In the Law covenant God laid down rules for warfare that he would approve, stipulating exemptions and the manner in which this warfare was to be carried out. Such were truly holy wars of Jehovah. That is not true of the carnal warfare of any nation today. However, with the establishing of the Christian congregation, a new situation came into existence. Christians are not under the Mosaic Law. Christ's followers were to make disciples of people of all nations; so worshipers of the true God would in time be found in all those nations. However, what is the motive of those nations when they go to war? Is it to carry out the will of the Creator of all the earth or is it to further some nationalistic interest? If true Christians in one nation were to go to war against another nation, they would be fighting against fellow believers, against people who prayed for help to the same God that they did. Appropriately, Christ directed his followers to lay down the sword. (Matt. 26:52) He himself, glorified in the heavens, would henceforth carry out the execution of those who showed defiance of the true God and His will. see 2 Thess. 1:6-8; Rev. 19:11-21. Some make use of Jesus words found at Luke 22:36-38 as a reason to support warfare, but notice the full context of that quote, Then he said to them: "But now let the one that has a purse take it up, likewise also a food pouch; and let the one having no sword sell his outer garment and buy one. For I tell YOU that this which is written must be accomplished in me, namely, "And he was reckoned with lawless ones". For that which concerns me is having an accomplishment"; Then they said: "Lord, look! here are two swords". He said to them: "It is enough". Having in mind his role in fulfilling prophecy, Jesus said to his disciples on the eve of his arrest: "Let the one having no sword sell his outer garment and buy one. For I tell you that this which is written must be accomplished in me, namely, "And he was reckoned with lawless ones". When they replied, "Lord, look! here are two swords", he said to them: "It is enough" (Luke 22:36-38) Enough for what? First, to fulfill Isaiah 53:12. Secondly, to drive home an important lesson for Christians. Surely there could have been no stronger reason for using a sword than protecting the Son of God himself! Yet it was not God's will for Jesus to be spared at that time. So when the apostle Peter used his sword against the slave of the high priest, Jesus told him: "Return your sword to its place, for all those who take the sword will perish by the sword". see (Matthew 26:52, 53; John 18:10, 11) Jesus thus made it plain that theocratic warfare from that time on was not to include the use of carnal weapons. Finally, "A careful review of all the information available goes to show that, until the time of Marcus Aurelius [Roman emperor from 161 to 180 C.E.], no Christian became a soldier; and no soldier, after becoming a Christian, remained in military service". Source -The Rise of Christianity (London, 1947), E. W. Barnes, p. 333. It is quite clear that the churches today that claim to be Christian have gotten away from that clear, basic Bible teaching.

God can and does end human life, because it belongs to him--he created it. He can also appoint agents to do it for him, if he sees fit. These agents can be angels. They can also be men. Before assuming you have the right to take a gun and blow some people away, you need to do a big Bible study with a respectworthy and educated minister--not some fanatic in a denomination of one church, either. (You don't have that right, by the way. It's restricted to legitimate governments and only for the most serious crimes--otherwise the government itself is sinning.)

The question is defective: why does it matter whether one is Christian or not? If its a sin, wouldn't it be a sin for all people? The other problem with the question is that it presumes all wars are the same, and all situations in which a person might be involved in a war are the same. Any atttempt to reduce the issue to such simple terms is doomed from the outset. Life isn't like that.

Perhaps a more appropriate question is: would a true Christian go to war and kill? If being a Christian means to be "in Christ" then clearly the answer is NO! Christ did not go to war and kill. Christ sacrificed himself instead of fighting. And as a Christian this should be your guide. As far as it being a sin to kill. We leave that for God to judge as no one else can answer for God. The bottom line is if you want to be a Christian then live as one. If you must be a warrior then be a warrior. But if you're wrestling between the two - remember you can't have it both ways.

Would Jesus?

Here's Ur Answer. Enjoy!!! John DOCTRINE OF MURDER A. Definition and Description. 1. Murder is the unlawful killing of another human being with malice of forethought, expressed or implied by the motivation of arrogance inside the cosmic system. The motivation comes from mental attitude sins, such as self-righteous arrogance, conspiracy arrogance, criminal arrogance, crusader arrogance, political arrogance, the arrogance of ignorance, the arrogance of unhappiness, or iconoclastic arrogance. 2. Hence, murder is both a sin and a crime related to cosmic involvement, and is often manifested in religion. All religions of the ancient world used human sacrifice. 3. Murder is the major attack on freedom and self-determination as a human issue in the angelic conflict. Murder is the invention of Satan and he is the motivator of murder. Murder is Satan's genius to invent a system to attack freedom and self-determination, Mt 26:52. 4. All killing is not murder. a. Capital punishment is taught in Rom 13:4 and Gen 9:5-6. (1) Animals that kill people as well as humans that kill people are to be executed. We are responsible for any decision we make to murder someone else. "Whoever sheds man's blood, by man [justice] his blood shall be shed [capital punishment]." (2) Man has the right to slaughter animals for food, Gen 9:3-4. But this does not give man the right to slaughter people. Man learned to kill man by watching man kill animals. (3) Capital punishment must be the result of due process of law, Num 35:30. There must be two witnesses. Homicide is first degree murder and must be punished by death, Num 35:16-18; Lev 24:17. b. Another area of legitimate killing is in battle. The soldier represents his country while functioning impersonally and professionally. It makes no difference who the object is (Christian or otherwise), you do your job and kill impersonally, not emotionally. A soldier functions impersonally and professionally to preserve the freedom of his nation, Josh 6:21, 8:24. 5. Israel, as the first client nation, was commanded to be prepared for war. Much of the establishment truth found in the Bible is first mentioned in relation to Israel. The bonified modus operandi of warfare is declared in Eccl 3:8, "There is a time for war." If you don't make time for war by being prepared, then there will never be peace. 6. Our Lord's rebuke to Peter in the garden was a warning against capital punishment because of criminal action (Peter's), not a warning about military killing. Mt 26:52, "Then Jesus said to him, `Return your sword to its scabbard, for all who draw the sword [in crime], shall die by the sword [in capital punishment].'" 7. Killing in battle is not murder. Ps 144:1, "Blessed be the Lord who trains my hands for war and my fingers for battle." 2 Sam 22:35, "He [God] trains my hands for battle." 8. Jesus Christ Himself holds the record for killing in battle in Isa 37:36, when He killed 185,000 Assyrian soldiers. But our Lord will break His own record at the Second Advent when He returns to terminate the Armageddon campaign, Rev 14:20, 19:11, 15; Isa 63:1-6; Ezek 39:11-13; Joel 2:20. 9. God is the source of some wars. 1 Chron 5:22, "Because the war was from the Lord." B. The Origin of Murder. 1. Jn 8:43-44, "Why do you not understand what I am teaching you? It is because you cannot hear My word. [They were in the cosmic system and refused to listen to what He said because it condemned them.] You are from your father the devil, and the policies of your father the devil you wish to accomplish. He was a murderer from the beginning; furthermore, he [Satan] does not stand in the truth, because there is no doctrine in him. Whenever he communicates the lie, he speaks from his own person, for he is a liar and the father of it [the lie]." Those who reject truth are easily motivated to murder. 2. 1 Jn 3:12, "Not as Cain who was motivated from that evil one and consequently he murdered his brother with a sacrificial knife. And why did he murder him? Because his deeds [moral self-righteousness seeking to impress God] were evil, but the deeds of his brother were honorable." Gen 4:5-8 gives the historical account of the first murder. C. Murder, violence, and terror is always occur when man becomes involved in the cosmic system. 1. "The way of Cain" is the pattern for murder, violence and terrorism. Jude 11, "But these reversionists malign what they do not understand. Furthermore, what things they do understand by natural instinct [emotion] as unreasonable creatures, by these false doctrines, they receive corruption. Woe to them for they have gone the way of Cain. They have rushed for illegal profit into Balaam's error. They have been destroyed in Korah's revolution." 2. The rise of crime and violence indicates national degeneration and the approach of historical catastrophe in the form of the fifth cycle of discipline, Jer 4:31. 3. Murder is always preceded by the mental attitude sin of arrogance. Rom 1:29, "Having been filled with all unrighteousness [lack of integrity] evil, greed, malice, full of jealousy, murder, strife, conspiracy, deceit, slanderers..." 4. This pattern of degeneration is developed into the destruction of the client nation. Hos 4:1-6, "My nation is destroyed from lack of knowledge of doctrine. Because you have rejected the principle of knowing doctrine, therefore I reject you from being a priest nation to Me." D. Murder is the only overt sin listed in the classification of the seven worst sins, Prov 6:16-19. E. Murder is therefore prohibited, Ex 20:13. "You will not murder" is the qal imperfect of RATZACH, not QATAL. Deut 5:17; Mt 5:21. F. Believers in the cosmic system are capable of murder. 1. David murdered in 2 Sam 12:9. Murder is a sin parlayed into evil through the interlock of the cosmic systems. 2. 1 Pet 4:15, "By no means let any of you suffer as a murder, or a thief, or a doer of evil, or one who sticks his nose in the affairs of others." 3. 1 Jn 3:15, "Everyone who hates his brother is a murderer. And you know that not every murderer has eternal life in him." Believers are murderers, but not all murderers are believers. G. Where guilt is established, the penalty for murder is death, Gen 9:6; Rom 13:3-4; Num 35:30-31; Mt 26:52.

Would it be better to practice civil disobedience and get in the way of the war in attempt to stop it?

Sin only relates to the Jews. Sin and Christians do not go together. So, no it is not a sin for a christian to go to war and kill the enemy. it becomes a matter of right and wrong with christians. it would be wrong to kill your fellow soldiers, but not wrong to kill the enemy.

no

i'm not christian but i know that thats a sin. cause your still ending a life.

No, it's only a sin for non Christians to go to war and kill...

No. There are places where the bible clearly condones violence. There are so many wars in it.

Yes, it's a sin. I stain myself with sin and damn myself (perhaps for eternity) so that others may live. Therein lies the measure of my sacrifice, and therein lies the lord's example I follow. ...WHAT, no Right-wing, Christian rebuttal?

The Bible never says that it is. Niether do the Catholic Church, the Eastern Orthodox Churches, the Coptic Church, the Nestorian Church, the Mar-Thomas Church, nor do the Lutheran, Calvinist/Presbyterian, Anglican/Episcopelian, Methodist, Baptist, Congregationalist or Church of Christ denominations. When the centurion came to Jesus and asked what he must do to be saved, Jesus didn't tell him to lay down his sword and leave the Roman army. When another centurion comes to Peter and asks the same thing, Peter baptizes him and his whole family, and then sends him back to his legion. So the answer would seem to be, "No, it is not."

It depends. The “just war” doctrine requires rigorous consideration to determine if defense by military force is legitimate. Offensive war is never justified. All the following considerations must be true to justify war: 1. The damage inflicted by the aggressor on the nation or community of nations must be lasting, grave, and certain; 2. All other means of putting an end to it must have been shown to be impractical or ineffective; 3. There must be serious prospects of success; 4. The use of arms must not produce evils and disorders graver than the evil to be eliminated.
