As Christians is it ok to kill our enemies ? Jesus told us to turn the other cheek, what if we are called to war or someone is trying to hurt our families?
The Biblical answer is IT DEPENDS. Let me explain...
"There is a time to kill and a time to heal." Wisdom in Ecclesiastes 3:3
"Put your sword back in its place," Jesus said to him, "for all who draw the sword will die by the sword" Jesus Christ in Matthew 26:52
"and if you don't have a sword, sell your cloak and buy one" Jesus Christ in Luke 22:36
So we see at one time Jesus said to put away the sword, but at another time, he said to pick it up. So is God's Word divided???? No. Never. He is just repeating what He said earlier... "There is A TIME to kill and A TIME to heal." So it depends on WHAT TIME it is.
In the Old Covenant (under the Law), killing was justified in specified cases. Since the death and resurrection of Jesus Christ, the only killing that is allowed by God is to stop the immediate murder of innocent, weaker people.
No Christian is EVER allowed to kill another human being simply for their beliefs, their words, for "God's will", or any anything EXCEPT to stop the immediate murder of another innocent, weaker person. God will 100% NEVER tell any Christian to kill for Him because it is Jesus Christ who already died and Jesus Christ alone who casts the wicked into the Lake of Fire.
So generally speaking the answer is "NO", no one led by the Spirit of God will ever again kill for God, for Christ, for Christianity, or for anything except to save innocent human life from immediate murder. From the time of Jesus Christ's death onward, no human WILL EVER again be called by God to kill for Him except in the rare, specific case of saving innocent, weaker humans from their immediate murder. In fact, the opposite is true. We are to give our lives as a sacrifice.
However, there remains Biblical, Legal justification to kill the oppressor if it is absolutely required to stop the imminent murder of another innocent, weaker person. This is what is referred to in Ecclesiastes 3:3 as "A time to kill".
Anyone who believes God/Allah/etc is calling them to kill for Him is 100% deceived by Lucifer. It will NEVER be God, except if it is to stop the immediate murder of the innocent.
PS I have a CCW permit in Indiana, but I only carry to defend people around me, never myself. God protects me. I protect others. And God has saved me from assaulters, gang members, angry drug dealers, angry pimps (I was sharing the Gospel with "their women" LOL), demon-possessed inpatients in psychiatric hospitals, crooked police who lied and beat me, and even a "Marked" man (he had THE LITERAL MARK, claiming about me "He's just jealous because Satan gave me this Mark and he cannot get it"), who full of satanic power, moving bibles telepathically, stopping the wind from blowing, and who held a box knife to my stomach but could not plunge it into me.
I don't need a piece of metal to defend myself. I have the Living Sword of Almighty God, the same Sword that guards the way to the Paradise of God, the same Sword that knocked over Jesus' attackers in John 18:6 and the same Sword has already stopped the Serpent/Dragon, the same Sword that will slay all followers of the Anti-Christ and False Prophet as shown in Revelation 19:21. Better yet, God Himself is "The wall of Fire about [me] and the Glory within [me]" as seen in Zechariah 2:5.
As David said in Psalm 118:6 "The LORD is with me; I will not be afraid. What can mere mortals do to me?"
