Ezekiel 36:25-26
 I will sprinkle clean water on you, and you will be clean;
I will cleanse you from all your impurities and from all your idols. 
I will give you a new heart and put a new spirit in you;
I will remove from you your heart of stone and give you a heart of flesh.

John 14:25-26 NIV
All this I have spoken while still with you. 
But the Advocate, the Holy Spirit, whom the Father will send in my name, 
will teach you all things and will remind you of everything I have said to you.

Holy Spirit,
make my heart open to the word of God,
make my heart open to goodness,
make my heart open to the beauty of God every day.

Prayer of Pope Francis
