We don't like to think about death. It makes us uncomfortable. As a kid I didn't like graveyards, they creeped me out. Now, part of my job is to go to graveyards and help with funerals...ironic, right?
But death is part of life. We all die, eventually. In fact, once we die, no matter if you are buried or cremated, you eventually become a pile of dust (ashes). Given enough time, your body will break down into the same thing that it was made from, dust.
Remember that in Genesis 2, God formed Adam (which literally means 'dirt') from the dust. We are made from dust and eventually that is what we turn back into. This is why you often hear the phrases "ashes to ashes, dust to dust."
The good news, for those who have put our trust in Christ, is that our bodies were never intended to last. We are told by Paul that our physical bodies are like a tent and eventually wear out. Some last a bit longer than others; but all earthly bodies eventually wear out. But we are promised heavenly ones that will last forever. No more dust, no more decay.
Death is inevitable; but our hope is in one who holds the keys to the kingdom of life everlasting.
