Holy Communion Prayer for Grace

How would the Church be different, in fact, how would the world be different, if every Catholic truly contemplated these words before receiving Our Blessed Lord at Holy Mass?  One who is not properly disposed to receive ought to be struck with terror at the mere thought of approaching the Sacred Host after reading these words....and yet....so many sacrilegious Communions!  O Lord, have mercy! 

"Let not the partaking of Thy Body, O Lord Jesus Christ, which I, though unworthy, presume to receive, turn to my judgment and condemnation; but let it, through Thy mercy, become a safeguard and remedy, both for soul and body; Who with God the Father, in the unity of the Holy Ghost, livest and reignest God, for ever and ever.  Amen."
