St. Therese loved nature, and often used the imagery of nature to explain how the Divine Presence is everywhere, and how everything is connected in God's loving care and arms. Therese saw herself as "the Little Flower of Jesus" because she was just like the simple wild flowers in forests and fields, unnoticed by the greater population, yet growing and giving glory to God. Therese did not see herself as a brilliant rose or an elegant lily, by simply as a small wildflower. This is how she understood herself before the Lord - simple and hidden, but blooming where God had planted her.

Therese believed passionately that Jesus was delighted in his "Little Flower," and just as a child can be fascinated by the grandeur of a simple flower, she believed that Jesus was fascinated by her as his "Little Flower." Therese understood that she was just like the tiny flower in the forest, surviving and flourishing through all the seasons of the year. Because of God's grace, she knew that she was stronger than she looked. Following the Carmelite tradition, Therese saw the world as God's garden, and each person being a different kind of flower, enhancing the variety and beauty which Jesus delighted in. When various people tried to explain her powerful inspiration and her place within the Church, it always seemed to come back to one title "the Little Flower."

In her autobiography, she beautifully explains this spirituality:

Jesus set before me the book of nature. I understand how all the flowers God has created are beautiful, how the splendour of the rose and the whiteness of the lily do not take away the perfume of the violet or the delightful simplicity of the daisy. I understand that if all flowers wanted to be roses, nature would lose her springtime beauty, and the fields would no longer be decked out with little wild flowers. So it is in the world of souls, Jesus' garden. He has created smaller ones and those must be content to be daisies or violets destined to give joy to God's glances when He looks down at His feet. Perfection consists in doing His will, in being what He wills us to be.
