2 Maccabees 15:17-19. Judas Maccabeus has just aroused his fighting men with inspirational words and the description of a dream that he had in which the prophet Jeremiah gave him a golden sword as a gift from God to strike down his adversaries. Now the men are greatly encouraged and they resolve to attack bravely, "because the city and the sanctuary and the temple were in danger. Their concern for wives and children, and also for brethren and relatives, lay upon them less heavily; their greatest and first fear was for the consecrated sanctuary." 

Judas' inspiring words and dream make his army wake his army from their fear. Rather than stay in the city and "wait and see" if and when the battle comes to them, they rally themselves to go out to the open country and attack the enemy. They are inspired mainly by fear of the sanctuary being destroyed. This shows they have their priorities straight. When God comes first in our hearts and minds, everything else (protection of family included) will flow from that.

Sometimes we cannot be pacifists; there is a time to go on the offensive. I have written about that before in When to Prepare for War. God does not want us to go around killing and warring with everyone, though, he really hates death, and he knows our proclivity to fight with each other, so he always makes it very clear when the time is right to go on the offensive. Here he did so by giving Judas a very clear dream where Jeremiah gave him a sword and told him to "strike down your adversaries."

Judas was such a good man and a good leader that God only had to give him the dream. He was able to convey the message and the necessity of the just fight to his men because they knew him and trusted him. This is another reason why we have to have good and honest leaders (which we don't right now, see There is No Truth or Justice in Them), and we should not blindly follow leaders when we know they are not honest (and very many of us are doing this now, to our and to our country's detriment).
