“Where is my faith?—even deep down, right in, there is nothing but emptiness & darkness. . . . If there be God, please forgive me.”

The author of those words might surprise you: Mother Teresa. Beloved and renowned as a tireless servant of the poor in Calcutta, India, Mother Teresa quietly waged a desperate war for her faith over five decades. After her 1997 death, that struggle came to light when portions of her journal were published in the book Come Be My Light.

What do we do with our doubts or feelings of God’s absence? Those moments may plague some believers more than others. But many faithful believers in Jesus may, at some point in their lives, experience moments or seasons of such doubts.

I’m thankful that Scripture has given us a beautiful, paradoxical prayer that expresses both faith and the lack thereof. In Mark 9, Jesus encounters a father whose son has been demonically tormented since childhood (v. 21). When Jesus says that the man must have faith (“Everything is possible for one who believes” v. 23), the man responds, “I do believe; help me overcome my unbelief!” (v. 24).

This honest, heartfelt plea invites those of us who struggle with doubt to give it to God, trusting that He can fortify our faith and hold on to us firmly amid the deepest, darkest valleys we will ever traverse.
