Throughout her life, Mother Teresa faced numerous challenges in her mission to serve the poor. One of the most significant obstacles was the lack of resources and support, particularly in the early years of her work in Calcutta, India. She often had to rely on donations and the goodwill of others to sustain her efforts, which were sometimes difficult to secure. Additionally, she encountered criticism for her views on poverty and suffering, with some arguing that her approach did not address the systemic issues contributing to these problems. Despite these challenges, Mother Teresa remained steadfast in her commitment, believing that her work was a calling from God and that every act of love, no matter how small, was worthwhile.
