After completing this schooling and doing some missions work within American inner cities, Maude was accepted to travel with the GMU to serve alongside a few struggling Christian missionaries in Morocco.
For the next fifty years of her life Maude Cary would minister to the rich and poor Muslims within Morocco attempting to bring them the Gospel message her school and parents had taught her.
A difficult start made Maude question her efffectivness in Morocco but she trusted that there would eventually be conversions from Islam to Christianity and stayed until she was too ill to serve.
Through the difficult start and her illness, Maude Cary became a Christian leader within Morocco for the Gospel Mission Union in charge of translation and Bible schools.
"[2] Maude's passion for the Christian mission movement was gained through the many traveling missionaries that visited their farm and stayed for a few days.
"At age of eighteen she enrolled at the GMU Bible Institute in Kansas City, Missouri, to be trained for a ministry in overseas missions.
She, along with others, would get up quite early, often missing meals, to spend time in prayer before God for the people around the world that had not heard the Gospel message.
Being sent first to Leavenworth, Kansas, Maude along with several other girls "held weekly Bible classes, visited homes and hospitals and conducted young people's missionary meetings.
There was a group of single women who could fully devote themselves to the mission and yet this quality "that made them... supremely capable for missionary service [was] viewed with suspicion by their weaker sisters and [was] threatening to their male colleagues.
"The fact that she outscored a male counterpart in language study, combined with her tendency toward gaiety, friendliness, and laughter and pride of dress, led to an internal mission board decision that she should return home.
At one point the political situation created such a dangerous environment that Maude and the other missionaries with her were forced to move to the coast away from the few Muslims that had befriended them.
The outcome looked bleak as there was no Christian church founded and Islam was still the primary belief system within the whole of Morocco.
But Maude Cary was convinced that it was worth the hard work and that one day the dominance that Islam had would be broken and would stand alongside Christianity.
[2] World War II began while Maude Cary was in Morocco and "all the missionaries were evacuated expect for herself and three other single women.
"Faithfully Maude witnessed for Christ to rich and poor, whether they listened eagerly or not... she worked extra hours translating and correcting hymns in the language of the common people.
"For three years she continued her ministry, but due to recurring health problems the mission began arranging for her retirement" and she departed in 1955.
"[6] Because this mission organization began close to Maude's home, and her parents were welcoming to missionaries, it would have been an obvious choice for her to attend the school they had started and then to later travel with them to Morocco.
