"The Sacraments which Our Lord instituted would not have saved us without the Holy Spirit. Even the death of Our Lord would have been useless to us without Him. Therefore Our Lord said to His Apostles, “It is good for you that I should go away; for if I did not go, the Consoler would not come. ” The descent of the Holy Ghost was required, to render fruitful that harvest of graces. It is like a grain of wheat–you cast it into the ground; yes, but it must have sun and rain to make it grow and come into ear. We should say every morning, “O God, send me Thy Spirit to teach me what I am and what Thou art.”"    - St John Vianney.
