Carole Zaleski in "First Things" wrote that Teresa converted "her feeling of abandonment by God into an act of abandonment to God."Read the whole thing
In many ways, her own sense of marginalization from God helped Mother Teresa to recognize loneliness in others. She proclaimed that there was "more hunger in the world for love and appreciation than for bread." She realized that rejection and abandonment was not only the province of lepers, but present even in the inner life of those who appear to be successful and privileged.
How many times have we gone to Mass, not "feeling it," as modern speak would put it. Our lips moving, our gestures mechanical, but we remain distant from the reality of God and his love for us. In that emptiness, temptation raises its head, suggesting that rather than practice this "hypocrisy," we should forego Mass and go out for a round of golf instead.
Mother Teresa lived her doubts, not for an hour on Sunday, but every day as she tended the poor and dying in utter, relentless squalor. Her example reaches across from Christians to non-Christians.
Benedict XVI, as Father Joseph Ratzinger, made the interesting point in his 1963 "Introduction to Christianity" that "both the believer and the unbeliever share each in his own way, doubt and belief." That led him to notice that doubt could be a possible "avenue of communication" between the two.
Time and time again, saints show us that when they suffer, the solution is to look outside oneself, not further within. St. Alfonso Liguori and St. John of the Cross both overcame their own troubles by focusing on their calling. As one religious sister acutely observed, when Teresa couldn't find Jesus in her prayer life, she found him in the faces of her fellow human beings.
Teresa eventually came to give a meaning to her trials. She saw them as a privilege, the gift of sharing in Christ's loneliness on the cross.
In his film "The Passion," Mel Gibson painted a wrenching image of Christ's agony in the garden of Gethsemane. Amid oppressive darkness, the sight of Jesus, abandoned by his apostles, struggling to continue with his mission, confronts viewers with the sense of desolation that accompanied his sacrifice.
Saints like Blessed Teresa, who faced loneliness in their self-sacrifice, experienced a unique sharing in the mystery of Christ's passion. Like the purest gold, they have been forged in hotter fires.
Particularly in our era that gives more weight to feelings than facts and to sensation rather than sense, Mother Teresa teaches the world to persevere through doubt, pain and loneliness. In the dark spiritual night of the 21st-century, Mother Teresa of Calcutta's example is a shining beacon to us all.
