Lott first taught at the Andhra Union Theological College, Dornakal from 1962 to 1964 along with Victor Premasagar, then Lecturer of Old Testament. The Principal of the College in Dornakal at that time was C. S. Sundaresan and the College was affiliated to the Senate of Serampore College. With the 1964 merger of the College in Dornakal into the newly formed ecumenical Andhra Christian Theological College in Rajahmundry, then headed by W. D. Coleman, Lott began taking classes in the river town of Rajahmundry. Later in 1972, Lott moved to Hyderabad along with the College when it was relocated to Hyderabad. During Lott's teaching career in Andhra Pradesh from 1962 to 1976, Lott taught New Testament and Religions to students pursuing L.Th., B.Th., and BD in Dornakal, Rajahmundry, and Hyderabad. In 1973, the Andhra Christian Theological College released Service for All Seasons, Lott's ecumenical worship book, which continues to be the primary worship book for students of Baptist, Lutheran, Anglican, Pentecostal, and Methodist backgrounds studying theology at the seminary in Hyderabad. The book was also adopted in a Church setting by the United Church in Defence Colony in Sainikpuri, Hyderabad, which serves an ecumenical congregation.
Karnataka
From 1977, Lott began teaching Religions at the United Theological College, Bengaluru along with G. D. Melanchthon, then Professor of Religions. The college enjoyed autonomous status with the Senate of Serampore College. Lott mentored students pursuing theology who came from diverse backgrounds. During the late 1970s during the Principalship of Joshua Russell Chandran, Lott encountered a student who would not complete his M.Th. thesis in Religions. The student's thesis was on self-proclaimed avatarSai Baba; when Lott offered revision suggestions, the student balked, since he believed that the "spirit of Sathya Sai Baba" had already taken control of the thesis and it could not be revised, lest the spirit got disturbed.
Higher studies
While teaching at Rajahmundry, Lott took study leave for the academic year 1969–1970 and completed postgraduate studies at the University of Lancaster in England. His dissertation was later published under the title God and the Universe in the Vedāntic Theology of Rāmānuja. In 1975, Lott again went on study leave to the University of Lancaster to pursue doctoral studies. His 1977 doctoral dissertation was entitled Vedāntic approaches to God.
