Padre Pio on Grace

"My soul is spurred on by the liveliest gratitude to attest that the Lord grants such grace to my soul without my meriting it. Far be it for me to consider myself superior to other souls for this reason. On the contrary, I believe that of all the people in the world, I am the one who serves the Lord least, and since the Lord gave such clarity to my soul through this grace, I acknowledge myself to be more obliged than any other soul to serve and love the Creator. For my soul, every minute of imperfection I commit is a sword of sorrow that pierces my heart."

Saint Padre Pio
