Explaining Death

So last night I was walking through the living room at my parents house, and due to an increase in family staying there for the holidays, my little 7 year old sister was sleeping on the couch. Well, I say sleeping, but in actuality, she was laying on the couch looking down at the floor with this doleful face that looked like a sky about to drop rain.
I naturally stooped down to talk to her, asking her what was wrong. I expected an answer about her having to go too bed early, or not getting to watch the PG-13 movie that was playing downstairs, or something of the sort. Instead, when she actually answered me this was what she said:
Tweeky: "Whenever I think of Mommy, I think she's dieing."
Me: "There's nothing wrong with Mom! She's not dieing!" (I don't know who taught me about dealing with kids... but I'm pretty sure none of them would have said to shut down the little kid first thing and tell them their logic is off!)
Tweeky: *starts crying for real, and buries her head in her pillow*
Me: *realizes my first mistake, and attempts to console her* "You know you don't have anything to be afraid of right?"
Tweeky: *looks at me incredulously with tears still streaming down her round cheeks*
Me: "Death isn't something to be afraid of. Death is just the end of one story. Its just when we stop being here on earth and start being with Jesus. And that is a happy thing! You know that right?" (I know she does because of the extensive conversations that I had with her when my Grandpa died.)
Tweeky: *bravely nods, before bursting into fresh tears*
Me: *begins praying (actually realized that I needed some extra help and grace to explain death to a 7 year old!! not sure why I didn't arrive at that conclusion earlier...) *starts to get a sense of the spiritual world going on around my little sister. Fear is lurking.* (but this is a 7 year old... how do you command demons to quit bothering a 7 year old? hmmm... here's an idea...)
Me: "Do you believe that Jesus loves you?"
Tweeky: *nods*
Me: "Do you believe that Jesus wants exactly what is good for you?"
Tweeky: *nods*
Me: "Do you believe that Jesus, because He loves you sooo much, and wants exactly what is perfect for you... do you believe that He knows the exact amount of days that you and Mom will have together?"
Tweeky: *sniffs, thinks for a bit, nods*
Me: "Theres a verse that says perfect love casts out fear. Jesus' Love is perfect; its the only love that is perfect. Janelle, if Jesus' Love is perfect, and you believe that Jesus loves you, and that He loves you perfectly, then you don't have anything to be afraid of! The fear is cast out by Jesus' perfect love!"
Tweeky: *sniffs again*
Me: "Can you pray and ask Jesus to help you not be afraid? Can you tell Him that you believe that His love is perfect, and that you know He loves you?"
Tweeky: *sniffs, nods, closes her eyes, sniffles come less frequently until they stop altogether*
Me: *continue praying against fear until I see her little forehead unwrinkle with peace*
Tweeky drifts off to sleep.

End of story? Yes and no. First of all, the main reason that I posted this on here was that I felt like it would help in my own healing, the way that I felt peace last night. Sitting on the floor in my living room explaining to my little sister, that death was not the end, was not scary, was only a doorway... and the closure and peace that I felt explaining God's love. No matter what the circumstances, His PERFECT love! Even when we don't understand it.
But I also want you all to know that the devil is real, and he doesn't have a single problem with attacking a 7 year old with fears and doubts! He's ruthless, and I hope your blood boils at the thought of him messing with one of His dear ones!! Mine sure does!
Are we being ready? Are we being vigilant? The battle is out there guys! And its freakin' messy! We're not against someone that's gonna play nice! Are we ready for the challenge??
