Hark! ten thousand voices sounding,
Far and wide throughout the sky;
’Tis the voice of joy abounding,
Jesus lives no more to die.

Jesus lives, His conflict over,
Lives to claim His great reward;
Angels round the Victor hover,
Crowding to behold their Lord.

Yonder throne for Him erected
Now becomes the Victor’s seat;
Lo, the Man on earth rejected,
Angels worship at His feet!

All the powers of Heav’n adore Him,
All obey His sovereign Word;
Day and night they cry before Him,
Holy, Holy, Holy Lord!
