Contextual Analysis of "dust to dust" in Lyrics

but even the darkest night will see the sun rise

i get knocked down then i get right back up

ashes to ashes

the life clock strikes and you obey

we turn to dust

my name is like the kiss of death

Skin to bone, steel to rust

Let tomorrow have its way

i know what you've got buried in the sand

it all comes down to who you really trust

a new spring

man to maker

ashes to ashes

whatever happens
