During the last war...?

I don't think so. We as mere humans, even in our glorified state with Christ, would not be able to war with the powers of darkness. That's why God created angels. Angels are Gods messangers, they do Gods bidding, just like demons do satans evil bidding. If you read in the Old Testament (I believe it's in Kings or Chronicles) there are cases that tell us the mere strength and power that even one angel has and it is far beyond our capability.

you mean the war after the 1000 year reign of christ? in that there is no mention of any war in the bible. It just says that when satan and his armiies surround God's city, Fire will come down from heaven and devour them.

Rev 20:9 And they went up on the breadth of the earth, and compassed the camp of the saints about, and the beloved city: and fire came down from God out of heaven, and devoured them.

Short answer: No.

Long answer: The "saints" you are referring to are not necessarily the "Christians" you may think you know... And it's not quite the 'war' that we can ever imagine it to be as to its magnitude and glory.

Besides, its outcome has already been foretold: the Good will conquer the Bad, who will be punished by sending them into oblivion and complete annihilation.

We will come with Him, but it will be Yeshua with the blood of His enemies on His vesture. It will be Yeshua who will save Israel in Bozrah. We will probably be His witnesses. Yeshua does not need any help, obviously. :)

My youth pastor told us we would. but i have honestly not read all of revolations to know that. I have always heard that revolations is so obscure, that we wont be able to figure it out until it actully happens.
