From Kenya, he returned to Geneva, Switzerland in 1993 to serve as Executive Director of WCC's Unit III - Justice, Peace and Creation. In 2003 he was elected General Secretary; his election was received with endorsement by global peers. During his acceptance speech he quoted the African proverb "If you want to walk fast, walk alone; but if you want to walk far, walk together". In this spirit, he worked to promote greater unity in the ecumenical movement through collaboration and dialogue. In 2005, he rejected the accusation of
anti-Zionism against the WCC and stated that anti-Semitism is a "sin against God and man" and "absolutely irreconcilable with the profession and practice of the Christian faith," quoting from the first assembly of the WCC in
Amsterdam in 1948. He has nevertheless been critical of the Israeli occupation of the Palestinian territories, calling it "a sin against God". The same year, he paid a tribute to Pope
John Paul II on behalf of his efforts for ecumenism. Kobia served as General Secretary for one term resigning in 2009. Kobia's resignation come as a surprise to the Central Committee, who stated that he had their "full support" despite harsh criticism from Rt. Rev. Martin Hein. In 2010, Kobia was appointed Ecumenical Special Envoy to Sudan by the All Africa Conference of Churches (AACC). In this current post, he continues his role as peacemaker and global leader. ==Selected publications==
