Even Mother Theresa Doubts

Time Magazine recently published an article of some letters written by Mother Theresa, where she painfully admits that she struggled with her faith. She, for 50 years, says that she lived in a painful darkness where she sometimes wondered about the existence of God. In the midst of all her great humanitarian work, in the name of Jesus, she admited to feeling forsaken, abandoned, empty, alone and ashamed.
At first, this article might make believers nervous. Mother Theresa was such a shining example of a life lived out in faith. If she struggled with her fundamental belief in God, then what about me? Right? Wrong! This article is exactly what a life lived out in faith should look like. Even Jesus Christ, God in flesh, as he was dying on the cross, cried out in a loud voice, "My God, my God, why have you abandoned me?" Matthew 27:46
If our goal as believers is to become more and more like Christ, then we have to expect that this life will parallel his suffering, his doubt, his feeling of forsakeness. When we are saved, there is no guarentee that our lives will be easy, or that we will never feel distant from God, or that we will never struggle with our faith. It is through these trials and times of hardship and seasons of spiritual darkness that we have to keep seeking and praying and trusting that God is there and will fulfill his promises. Those will be the times that will truly strenghten and solidify our faith.
In one of her later letters, Mother Theresa writes about why she believes that she struggeled so many years with feeling the absence and lonliness from God....
"I can't express in words — the gratitude I owe you for your kindness to me — for the first time in ... years — I have come to love the darkness — for I believe now that it is part of a very, very small part of Jesus' darkness & pain on earth. You have taught me to accept it [as] a 'spiritual side of your work' as you wrote — Today really I felt a deep joy — that Jesus can't go anymore through the agony — but that He wants to go through it in me.
— to Neuner, Circa 1961
