The gospel was preached in Namibia in the first half of the 19th century and a strong Church emerged. However, the influence of liberal theology led to a weakening of many churches and a large number of Christians became involved in ancestor worship. Many are nominally Christian, but they lack understanding and experience of the new birth, as well as a personal living relationship with God through Jesus Christ.

Many syncretistic churches exist and the great need is for clear biblical teaching and training for church leaders. Africa Evangelical Fellowship (AEF), now merged with the Society of International Ministries (SIM), sent missionaries there in the late sixties. In 1986 AIM joined with AEF to form a much larger team which works in Windhoek, Grootfontein, and in the northeast regions of the Kavango and Caprivi.

The Evangelical Bible Church (EBC) was formed under national leadership with branches in the areas where SIM and AIM work. Two Bible colleges, one in Windhoek and one at Rundu in the north, have links with this church. AIM has over twenty missionaries in the country involved in Bible teaching and church work.

HIV/AIDS is one of the greatest challenges facing Namibia in the new millennium. Ranked by the UN as having the third highest incidence in the world per percentage of the population of those suffering from HIV/AIDS sufferers, Namibia faces a reduction of the present population by a startling 50 percent by the year 2010 through AIDS deaths. The joint SIM/AIM team is working together with the EBC to develop an appropriate program to respond to the crisis.
