Currently the secular Israel is not children of God, so can't use ot examples.We have all had this conversation before.
While God/Jesus doesn't prefer war, sometimes it is necessary for God/Jesus to protect His people from Satan and anyone who wants to do them harm, regardless of their current state. Especially, when we already know that God has a specific plan and purpose for these people based on what has been written. Don't forget that while Jesus will ultimately bring peace into the world, He has to do it by returning with the Wrath of God. Does that mean He won't use people on the earth to carry out part of those plans before He returns to finish it off? The answer is "No".
Let's look at some history in the Bible:
God personally waged war against the Egyptians by destroying their army in the Red Sea and later commanded Israel to execute judgment on the Canaanites, who were deemed exceedingly wicked. In these conquests, God provided specific battle strategies, such as the collapse of Jericho’s walls after the Israelites marched and shouted, demonstrating that victory relied on divine intervention rather than conventional military might.
God directed ancient Israel’s armies to defend their land and enforce His laws, often intervening supernaturally to secure victory. Key examples include Gideon’s 300 men defeating the Midianites to prove God saves through His power, and King David receiving divine battle tactics to defeat the Philistines. God also fought for Israel without their direct combat, such as when He caused a coalition of enemies to rout themselves during King Jehoshaphat’s reign.
Heavenly hosts and angelic armies are depicted as executing God’s will alongside or instead of human forces. The commander of the Lord’s army appeared to Joshua to lead the conquest of Canaan, and Elisha’s servant saw mountains filled with "horses and chariots of fire" to protect Israel. Ultimately, biblical texts portray God as the Supreme Leader who determines when to wage war, ensuring that His people trust in His power rather than their own strength.
Crossing the red Sea, at that time they were considered God's people.
Jericho wall, at that time they were God's people, following specific God's order.
Current Israel, not God's people, they are grabbing land, murdering people for self wealth gaining. Where in Bible God tell secular people to kill in the name of God?
