What is the theme of the poem Adieu, Farewell Earth's Bliss by Thomas Nashe?

Adieu, farewell earth's bliss,
This world uncertain is:
Fond are life's lustful joys,
Death proves them all but toys,
None from his darts can fly -
I am sick, I must die:

Lord, have mercy on us!
Rich men, trust not in wealth,
Gold cannot buy you health,
Physic himself must fade.
All things to end are made,
The plague full swift goes by -
I am sick, I must die:
Lord, have mercy on us!

Beauty is but a flower,
Which wrinkles will devour;
Brightness falls from the air,
Queens have died young and fair,
Dust hath closed Helen's eye -
I am sick, I must die:
Lord, have mercy on us!

Strength stoops unto the grave,
Worms feed on Hector brave;
Swords may not fight with fate,
Earth still holds ope her gate,
Come, come, the bells do cry -
I am sick, I must die:
Lord, have mercy on us!

Wit with his wantonness
Tasteth death's bitterness;
Hell's executioner
Hath no ears for to hear
What vain art can reply -
I am sick, I must die:
Lord, have mercy on us!

Haste therefore each degree
To welcome destiny:
Heaven is our heritage,
Earth but a player's stage;
Mount we unto the sky -
I am sick, I must die:
Lord, have mercy on us!
