o thou who camest from above the pure celestial fire to impart kindle a flame of sacred love on the mean altar of my heart  there let it for thy glory burn with inextinguishable blaze and trembling to its source return in humble prayer and fervent praise  jesus confirm my hearts desire to work and speak and think for thee still let me guard the holy fire and still stir up thy gift in me  ready for all thy perfect will my acts of faith and love repeat till death thy endless mercies seal and make the sacrifice complete
