In Estonia the partner church of LEAF is The Evangelical Lutheran Church of Estonia, (ELCE). LEAF started working in the country in 2005.

In Estonia, the Christian tradition was broken for 50 years during the regime of the Soviet Union. Spiritual emptiness tends to be filled with all kinds of new religions. The need for mission work is obvious and the Evangelical Lutheran Church of Estonia has welcomed missionaries to help.

LEAF missionaries have pastoral duties in the local parishes and coordinating work for child, youth and other groups of different interests. Moreover, they actively contribute educational writings to Christian publications.
