I really do not like sharing personal experiences due to the fact that they can be dismissed so readily and yet they are very personal to the one that has them. Regardless, I will tell you of one instance that gave me knowledge that God cares for each of us on a very personal level.
Background: My husband and I left our lives in another state so that our daughter would be closer to extended family. We were a little concerned about starting somewhere else and had been praying about it. We were hoping that God would give us some sort of sign that we were doing the right thing. It wasn't long that we started seeing the northern lights spread across the sky. It is pretty rare in this area, in fact few people have ever seen them. Cars were pulling over to stand and watch. We thought this might be the sign we were looking for.
So jump ahead some seven years later. My husband is a painter and he and I were going to a near by town to see if he could get some art sold. I had done some sculpting as well and we were in need of cash. We had been trying to live on art and I wasn't so sure we should be. (Wasn't giving us much of an income) So we tried all the places we thought might be interested and sold a few things but it was pretty much a disappointment. My mother-in-law and husband were in the front seat, while I sat rather dejected in the back. I was asking God what we should do and I remembered for some reason the time earlier when we saw the northern lights and how we felt it was a sign. I asked God that if we were doing the right thing to show me the Northern lights again. We were just leaving a small town and so when at first I saw a red haze I questioned if I was just seeing the lights from town. I even asked my husband if he thought the sky was turning red. He said he thought it was just the lights from the town. So I sat there a few more minutes still praying and then the sky just went crazy. Red and green swept across the sky. It was incredible. I couldn't believe my eyes. The lights continued until we pulled into our driveway and then just stopped.
I have no proof of this. It is one of those things that you can dismiss, but I am being perfectly honest here. It happened.
For starters, I am not about to question the importance of this event for you, and I am not going to be saying you are a liar or are making it all up. Please keep that in mind, because I am just going to point out a few areas where I would have some questions, and why.
For starters, the initial time the Northern Lights showed up as a sign, you prayed and then "It wasn't long" before you started seeing them. How long? A minute? Ten? Thirty? Because it's been shown that people have a widely varying window on when something happens to consider it linked to something else. Second, you say that the Northern Lights are "pretty rare" in that area. How rare? How often do the Northern Lights show up around there? Once a year? Once every few months? Once a decade? What about in the specific area you were in at the time?
The second time you saw the Northern Lights after praying for them as a sign, again, how soon after praying did it actually happen? How soon after you got home did they disappear? How rare are the Northern Lights in that part of Nebraska? Because a quick search on the issue shows that there are a good number of things named after the Northern Lights, from streets to malls, which indicates that they maybe aren't that rare. Other questions I might have are whether you were in a city or out in the country when you were driving back from selling the art. And what sort of area you live in (urban or suburban or rural), the streetlight situation on the streets leading to you home, and the lighting situation in your driveway and around your house. Because the Northern Lights are more visible in the dark of the country than the brightness of the city.
That's where my questions would come from. The way you tell the story, the implication seems to be that the Northern Lights went away the instant you got home, with the underlying meaning that God ended His sign for you. But how much leeway should be given to the instant when you got home? And was it that the Northern Lights went away, or could it be that you arrived at a place of greater light pollution that prevented you from seeing them?
Further questions would be around whether those specific Northern Lights were visible elsewhere around the world that night, whether they coincided with the appropriate sort of sun activity that produces the Northern Lights, and whether they had been predicted beforehand based on that sun activity.
