O Lord our Governor, Ruler of all nations: Look favourably upon thy servant Barack as he rededicates himself to the service of our country. Grant him the wisdom, courage, strength, and humility to lead our country in the paths of righteousness, that we may dwell in peace and prosperity, and be an example to all peoples; through Jesus Christ our Lord. Amen.
