In 1980 Führer helped to organize "peace prayers" as part of a joint protest action of Protestant youth organisations. Starting on 20 September 1982, the peace prayers were held every Monday in the Nikolai Church in Leipzig focusing against the Cold War. In 1987 he organized a pilgrimage in the context of the Olof Palme Peace March. In 1988 he moderated prayers for the arrested protesters of the :de:Liebknecht-Luxemburg-Demonstration|Liebknecht-Luxemburg-Demonstrations. On 19 February 1988 Führer held a speech Living and Staying in the GDR in the Nikolai Church. Many opposition members attended the speech which marks a special date of east German resistance against the Honecker Regime.
During the first months of 1989 the East German authorities, especially the Stasi, imposed more and more pressure to stop the "Peace Prayers" in Leipzig. They controlled access roads and arrested random "suspects" inside and outside the church. However, they were unsuccessful: the Monday prayers continued with an increasing number of attendees. On 9 October troops of the army, police and Stasi officers arrived in front of the church. About 1,000 members of the SED were ordered into the church. Nearly to the end of the Peace Prayers a manifest was read out, written by Kurt Masur, Bernd-Lutz Lange, Peter Zimmermann and three low-rank leaders of the SED, appealing to all attendees not to use force and to stay peaceful. The demonstration of about 70,000 people right after the prayers was in fact peaceful. The slogan "No Violence!" was used by more than 300,000 people during the following demonstrations. The whole East German revolution remained peaceful.
After reunification
After 1989 Führer became an advocate for unemployed people; he was a co-founder of the "Church Initiative for the Jobless, Leipzig". In 2004 he again organized Monday demonstrations against the dismantling of the welfare state and the Hartz IV reforms. He also continued to hold regular Peace Prayers. On 30 March 2008 he held his final service in the Nikolai Church and retired.
