Here are also some good scriptures to think about in regard to this matter that i have found to be helpful.
John 18:36 Jesus answered, My kingdom is not of this world: if my kingdom were of this world, then would my servants fight, that I should not be delivered to the Jews: but now is my kingdom not from hence.
2Co 5:20 Now then we are ambassadors for Christ, as though God did beseech you by us: we pray you in Christ’s stead, be ye reconciled to God.
2Tim 2:3,4 Thou therefore endure hardness, as a good soldier of Jesus Christ.
No man that warreth entangleth himself with the affairs of this life; that he may please him who hath chosen him to be a soldier.
I think that these verses clearly show that --even as Jesus said-- we are not of this world, but are living for a world that is to come.
as ambassadors and soldiers of Jesus Christ, how can we entangle ourselves in the things of this world???
Kent Hovind preached a sermon called "Where's the Bride?" He took the story of Abraham's servant sent out to find a wife for His son, and changed the ending of the story with the servant coming back empty handed but with many stories to tell of things they had done while in Mesopotamia. Abraham
is saddened by this report and says "you know, thats great and all, but thats not why you were there, thats not what i sent you for, i sent you to get a bride for my son."
God has also chosen us out of the world, we are now "strangers and pilgrims on the earth", "our conversation is in heaven." How can we entangle ourselves in the things of this life?
We have been sent on a mission, and this mission conflicts with the agenda of this world.
Sure God commanded the Israelites to fight and war. oh, that reminds me of something...
A group of us were coming back from ministering at a homeless shelter in downtown Chicago, we stopped at a hamburger shop for a snack, and as we began eating the girl sitting next to me asked me this question: "What do you think of women in the military?" "well," i said "before i can answer that question, i think you should first ask me what i think about the military, period." at that a shocked expression came over her face and she exclaimed, "what? are you a Mennonite or something? how can you not agree with joining the military? don't you know that God commanded Moses and Joshua to destroy the nations that inhabited the promised land?" and so i countered her question with another question "and why do you think that God wanted them to do that?" she replied "well because they were wicked nations that needed to be destroyed and God used the israelites as His instruments to punish these wicked nations."
"so God wanted the israelites to war because these nations were wicked and needed to be destroyed?"
"yes"
"and is Iraq a wicked nation?"
"yes, and thats why our troops are there, i think that God is using the US as His judgment on them."
"But don't you think that the US is also a wicked nation?"
"well... yes. but..."
"well don't you think wicked nations ought to be destroyed?"
she didn't have much to say after that. (btw, asking questions without actually making any concrete statements is a good way to bring people to their own conclusions... or force them to your own ;-) )
all that to say that there is not much argument for Christians fighting in the military.
remember, we are not of this world, and the world does not comprehend our thinking, they don't know us because they didn't know Him.
Blessings to all.
