1 O thou who camest from above the fire celestial to impart, kindle a flame of sacred love on the mean altar of my heart! 2 There let it for thy glory burn with inextinguishable blaze, and trembling to its source return in humble prayer and fervent praise. 3 Jesus, confirm my heart's desire to work, and speak, and think for thee; still let me guard the holy fire, and still stir up the gift in me. 4 Ready for all thy perfect will, my acts of faith and love repeat; till death thy endless mercies seal, and make the sacrifice complete.
