To a Lady asking him how long he would love her

IT is not, Celia, in our power
To say how long our love will last;
It may be we within this hour
May lose those joys we now do taste;
The Blessed, that immortal be,
From change in love are only free.

Then since we mortal lovers are,
Ask not how long our love will last;
But while it does, let us take care
Each minute be with pleasure past:
Were it not madness to deny
To live because we're sure to die?
