He was hurled to the earth, and his angels with him.”

Submitting to governing authorities -

Romans 13:1-3 reads: “Let everyone be subject to the governing authorities, for there is no authority except that which God has established. The authorities that exist have been established by God. Consequently, whoever rebels against the authority is rebelling against what God has instituted, and those who do so will bring judgment on themselves.”

Love your enemies -

Matthew 5:38-45 gives us a new perspective on the God of the Old Testament when it comes to war. "You have heard that it was said, 'Eye for eye, and tooth for tooth.' But I tell you, Do not resist an evil person. If someone strikes you on the right cheek, turn to him the other also. And if someone wants to sue you and take your tunic, let him have your cloak as well. If someone forces you to go one mile, go with him two miles.”

Love your enemies -

It continues: “Give to the one who asks you, and do not turn away from the one who wants to borrow from you. You have heard that it was said, 'Love your neighbor and hate your enemy.' But I tell you: Love your enemies and pray for those who persecute you, that you may be sons of your Father in heaven.”

Be at peace -

Overcome evil with good -

He continues: “Never take your own revenge, beloved, but leave room for the wrath of God, for it is written, 'Vengeance is Mine, I will repay,' says the Lord. 'But if your enemy is hungry, feed him, and if he is thirsty, give him a drink; for in so doing you will heap burning coals upon his head.' Do not be overcome by evil, but overcome evil with good.”

War is inevitable -

It's always happened and it always will. Jesus Himself spoke about it. Matthew 24:6 reads" “You will hear of wars and rumors of wars, but see to it that you are not alarmed. Such things must happen, but the end is still to come.”

Prophecy? -

Pacifism -

Pacifism -

Christian pacifists also base their stance on the belief that the kingdom of God is not on Earth, as per John 18:36, which reads, “Jesus said, 'My kingdom is not of this world. If it were, my servants would fight to prevent my arrest by the Jewish leaders. But now my kingdom is from another place.'"

Holy war -

Paul the Apostle makes a reference to a holy war between good and evil in 2 Corinthians 10:3-4: “For though we live in the world, we do not wage war as the world does. The weapons we fight with are not the weapons of the world. On the contrary, they have divine power to demolish strongholds.”

Just war theory -

The just war theory is a philosophy that emerged many years ago. Its principles can be traced back to classical Greek and Roman philosophers, but Christian theologians such as Augustine and Thomas Aquinas expanded on it.

Just war theory -

“Just” doesn’t mean “good.” The whole idea still condemns war, but addresses it from a "lesser evil" standpoint.  The theory tries to reconcile the ideas that killing people is bad, but that sometimes the use of force is inevitable. It provides guidelines on how to conduct war in a more just way.
