Born in what is present-day Belarus, Deyneka immigrated to Chicago in 1914, where he worked in a machine shop. Deyneka married Vera Demidovich on May 23, 1926, before working in Latvia and Estonia as field secretary for the All-Russian Evangelical Union and then engaging in a number of preaching tours to the worldwide Russian diaspora.

Two years later, they incorporated as the Russian Gospel Association, the name of which was changed to the Slavic Gospel Association (SGA) in 1949.
Deyneka wrote several books, including an autobiography.
