A charge to keep I have,
A God to glorify;
A never-dying-soul to save,
And fit it for the sky: -- -

2 To serve the present age,
My calling to fulfill, --
Oh! may it all my powers engage --
To do my Master's will.

3 Arm me with jealous care,
As in thy sight to live;
And, oh, thy servant, Lord! prepare
A strict account to give.

4 Help me to watch and pray,
And on thyself rely;
Assured, if I my trust betray,
I shall forever die.

Charles Wesley, 1762.
