My vote would go to Mother Teresa of Calcutta for her life of selfless work among the poor outcasts of the world. Another candidate would be Father Damien de Veuster of Molokai. The list is long.

The line is from the Miraculous Invocation to St. Therese(Therese of Lisieux):
O Glorious St. Therese, whom Almighty God has raised up to aid and inspire the human family, I implore your Miraculous Intercession. You are so powerful in obtaining every need of body and spirit from the Heart of God. Holy Mother Church proclaims you "Prodigy of Miracles ... The Greatest Saint of Modern Times." Now I fervently beseech you to answer my petition (mention here) and to carry out your promises of spending Heaven doing good upon earth ... of letting fall from Heaven a Shower of Roses. Little Flower, give me your childlike faith, to see the Face of God in the people and experiences of my life, and to love God with full confidence. St. Therese, my Carmelite Sister, I will fulfill your plea "to be made know everywhere" and I will continue to lead others to Jesus through you. Amen.
