1944. He worked in Pumwani under Reverend Pitway of Nairobi diocese and Mr. Colonel Elijah Gachanja. In 1943 Reverend Daudi was sent to Maasai land because there was no preacher over there due to the high number of lions and water shortage. Bringing change and Christianity to Maasai land Reverend Mokinyo build the first church in Kajiado at around 1944, the church was located next to the present day maasai store (Shopping centre in Kajiado). During this time, the construction of Emanuel church was underway as he continued spreading the gospel. He got an offer from the D.C to become the Maasai District Officer, but turned it down because he was already dedicated to working for God. Reverend Mokinyo was offered some other work opportunities while he spread the Gospel, jobs such as a Maasai store clerk and working for Kenya Marble Quarry(KMQ) company, but he also turned them down for the same reason. Additionally, in 1952, the Magadi Soda Company gave him a permit to transport firewood and sand, however, he delegated the job to his brother Mr Maora, who worked with around 300 men, most of them from the tribe of Watende in Tanzania and the Kamba from Kenya. Mr. Maora went on to become a headman in his work field, then later he became chief, and afterwards the Paramount chief. In 1957, he acquired a farm in Maasai land (loodokilani). Apart from the scarcity of water, the place was also known for the high number of lions.
