Since life in sorrow must be spent,
So be it--I am well content,
And meekly wait my last remove,
Seeking only growth in love.
No bliss I seek, but to fulfil
In life, in death, thy lovely will;
No succours in my woes I want,
Save what thou art pleased to grant.
Our days are numbered, let us spare
Our anxious hearts a needless care:
'Tis thine to number out our days;
Ours to give them to thy praise.
Love is our only business here,
Love, simple, constant, and sincere;
O blessed days, thy servants see,
Spent, O Lord! in pleasing thee!
William Cowper
