I don't think a precedent can be set for owning or not owning. Personally I didn't so much care about concealed carrying. Then I started having really vivid clear dreams for about a year and a half to get a concealed handgun license. I finally took the class, got my license, and aurora co happened the week after I received it. I had no idea what handgun to buy so I prayed and asked, "God help, You told me to do this, what handgun should I buy?" I had a dream that night where I went to a gun shop and was told to buy a sig p229. I woke up thought wow, went back to sleep and had another dream where a friend said to me in the dream, "Remember that dream you just had about buying a sig p229, you need to pay attention to it." So I bought a sig p229 and carry it everyday.
Same thing happened with ar15's. Had a dream that I needed to buy an ar15. Confused and not wanting an AR15 i couldn't bring myself to buy one. Two days later newtown shooting happened and you couldn't find one anywhere. A couple months went by though and I felt like I should go to academy one morning, no body was there and they had just gotten in a shipment of a couple AR's so I picked one up.
My point isn't to set a precedent but I think we should approach the Lord and ask, "God what should I do? I know what the law is but I know our country doesn't always have laws that agree with Your opinions. Help me." If we want to know what He thinks and we wait on Him, He will give us insight and wisdom on how to live and move forward.
