Livingstone, who was brought up in the evangelical tradition of Calvinism, decided at an early age that he wanted to become a medical missionary. To prepare himself, he studied Greek, theology, and medicine for two years in Glasgow. In 1838, he was accepted by the LMS. He initially wanted to go to China, but a meeting with Robert Moffat, the notable Scottish missionary in Africa, convinced him that Africa would be his sphere of service. On 20 November 1840, he was ordained as a missionary, and on 14 March 1841 he arrived in Cape Town. Supported in his religious fervor by philanthropic ideals to bestow the values of liberty, humanity, and justice on the heathens in Africa, Livingstone chose as his mission field an area bordering on the Kalahari Desert in the country now known as Botswana.
