The simple truth of scripture shows that in times of conflict God moved supernaturally and always, but always did one of two things.
1. Supernaturally protected His people. Like the Children of Israel crossing the Red Sea and Jehosaphat when he was surrounded.
or
2. God gave man wisdom and strength to defend himself. Remember why Moses was raising his arms? Because the people were defending themselves. Remember Abraham, who conquered two cities and carries away it's goods at God's direction.
But some would say, that changed in the New Testament.
Was tolerance preached - you bet
Did Jesus say we should love our enemies? You bet
Did Jesus ever command His followers to take up arms?
Let's look:
Luke 22:35 And He said to them, “When I sent you without money bag, knapsack, and sandals, did you lack anything?”
So they said, “Nothing.”
36 Then He said to them, “But now, he who has a money bag, let him take it, and likewise a knapsack; and he who has no sword, let him sell his garment and buy one. 37 For I say to you that this which is written must still be accomplished in Me: ‘And He was numbered with the transgressors.’ For the things concerning Me have an end.”
I encourage you, read the verses before and after. Times changed, Jesus was telling them to get ready and get armed. What happened next? An armed confrontation in the Garden. A 9 year old can clearly see that. Wouldn't this have been the time to remind them not to resist evil? Wouldn't this been the perfect time for Jesus tell them to let their enemies hit their other cheek? That's what He taught. Instead, He instructed them to go get a weapon.
Look at the first great dispersal and how many Christian patriarcs were commanders of armies. Look at history and how many people, military and otherwise cite God's provision of both supernatural protection and provision of wisdom and strength to win battles.
Now some might say that is different from day to day life, and I would disagree wholeheartedly. There is plenty of first hand testimonies - even here on CF of how God spoke to people and did once again both - supernaturally provided for their safety or supernaturally gave them wisdom and strength to overcome.
