knock and it shall be opened to you."

your most holy Mother,
I knock, I seek and I ask
that my prayer be granted.
(State your request.)
O Jesus, you said:
"All that you ask the Father in my name
He will grant you."
Through the intercession of Mary,
your most holy Mother,
I humbly and urgently ask
your Father in your name
that my prayer be granted.
(Repeat your request.)
O Jesus, you said:
"Heaven and earth shall pass away,
but my world shall not pass."
Through the intercession of Mary,
your most holy Mother,
I feel confident that my prayer will be granted.
(Repeat your request.)
Amen.
