Following, are some of the petitions the priest makes to God when he blesses water:

”O God… Grant that this creature of Thine (water) may be endowed with divine grace to drive away devils and to cast out diseases, that whatever in the houses or possessions of the faithful may be sprinkled by this water, so that health which they seek by calling upon Thy Holy Name may be guarded from all assaults.”

The devil hates holy water because of its power over him. He cannot long abide in a place or near a person that is often sprinkled with blessed water. Holy Water, sprinkled with faith and piety, can move the Sacred Heart to bless your loved ones, present or absent, and protect them from all harm of soul and body. When worry and fear take possession of you, give your dear ones the benefit of the Church’s prayer. If we desire to make a host or intercessors for ourselves, let us never forget them at the Holy Water font. The holy souls nearest to Heaven may need the sprinkling of only one drop to release them.
