In the history of the Church there are many examples of true and strong faith in Jesus Christ. Amidst them there is St. Therese of Lisieux. Despite her short life, her example of faith went long down in history. But before the history of her faith and spirituality, there is the history of their growth. In this paper there is pointed the long road from a childhood mind toward a pillar of faith. It begins with a troubled childhood marked by the loss of parents. Then follows the sensitive period of a teenager fearing especially of being abandoned, continuing with youth, a time of growing and developing not only a strong faith, but also a fiery love for God. These stages, step by step, lead to a maturity of faith, a maturity that she achieves at a very young age, considering the fact that she was only 24 years old when she died.
