By Charles Wesley

      1.
      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;
      O 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.
