A charge to keep I have, A God to glorify, A never-dying soul to save, And fit it for the sky. To serve the present age, My calling to fulfill: Oh, may it all my pow’rs engage To do my Master’s will! Arm me with jealous care, As in Thy sight to live; And O Thy servant, Lord, prepare A strict account to give! Help me to watch and pray, And on Thyself rely, Assured, if I my trust betray, I shall forever die.
