Fleeting Shadow Lyrics

Like a fleeting shadow
is my life on the earth
I grow up like a flower
that withers away
Soon the last crumb of sand
flows away from my hand
It's time for me to go
trough the death's stream
Each man's life
is like a short breath,
the span of your years
is as nothing before God
Man's days are determined
all have to die away
Hide from death no-one can
helpless is a mortal man

Who can tell the meaning of this short wandering?
Is there someone who can say am I living to die away?

Before the oceans' born
were you, o Lord,
you've created everything
by your mighty word
The heavens and the earth
are the works of your hand
You've founded the world
and all that's in it
Thousand years in your sight
is like a day has just come by
Your eternal word will bring
all secrets to the light
Great and awesome
are you, oh God
So what's a son of man
that you care of him?

Tech me, o Lord, to number my days aright
Help me to live this life for the glory of yours
