Rest In Peace?

What is RIP? What does this mean? Rest in Peace. I mean... of course it is a gesture of kindness. I just do not think people understand the simplicity and vagueness of this idiom, or the lack of reference to eternal life.

"RIP (Rest In Peace) - to lie dead peacefully for eternity."

Now do you get it? Why would someone say RIP? It has no hope. No joy. It simply is a wish for the BODY to lie in peace... the body... the temple... the part of us that dies.
My theory on this matter is simply lack of education in definition of the term. People just think RIP is an expression of sincerity. To give people a sense of hope or happy feeling. Most people take it that way... not me.
If you want to show sincerity or give someone hope, say something about the soul, or eternal life after this test.

We should say LIP! (Live In Peace!) Why? Because the body dies. This is fact. But the soul never dies. Also fact. So after the death of our body, your soul either goes to Heaven or Hell. So why not say LIP? I declare that from here on out, I will NEVER say RIP. The body does not need rest. It does not need peace. Your soul needs rest and your soul needs peace!

LIP CASSIE! Live in Peace.
