God supported the Children of Israel in war.
God will also support others who have to use force.
If you allow yourself to be killed without putting up a fight, it is suicide. Do you think suicide is sanctioned by God? If a person allows his family to be killed without planning for their safety and lifting a finger, he has shirked his duty. If we allow our neighbors or community to be attacked by evil people without confronting them, we are also guilty. The same goes for our nation.
Yes, there is a good and an evil. Good must stand up to evil. God sanctions that. God is the same today as He was in the past. He will be the same tomorrow. He backed Israel in war.
IMO < we have a duty to protect ourselves, our loved ones, our community, and our nation.
Every God fearing man should own weapons, and make sure to use them in a manner that God could approve of.
So Christ, whom had all the resources of heaven at his disposal, committed suicide by submitting to his death on the cross?
So Christ, who initially sent his disciples out with swords, and then his disciples had no swords, is not sending a message as to the later times for Israel and all true Christians as to whom they must trust in?
