University College, London was known for being “godless” being strongly influenced by rationalist and communist ideas, and lacking a chapel for students to use.
Feeling uneasy about her current stance as a human being without a type of faith, she converted to Christianity, claiming she had a vision of an encounter with Jesus Christ; the date was February 1946.
Vivienne began taking evening classes at London Bible College and started learning New Testament Greek.
Her intelligence and eagerness to learn and expand her knowledge soon gained her an admirable reputation as well as invitations to churches in nearby towns to preach to the congregations.
Vivienne sought to write and have books published for the Christian church in Pakistan, with the contents varying from helping people relate to Muslims, attempting to cross cultural barriers, dealing with spiritual warfare, as well as various Biblical studies.
Some of Vivienne’s articles subsequently appeared in about twenty languages including Korean, Kannada, Urdu, Dutch and English.
In 1993, Vivienne retired from Interserve but continued her writing, itinerant teaching, and training leaders for Christian ministry among Muslims.
