Jonathan will hand over power to the President-elect, Gen. Muhammadu Buhari, on May 29, 2015.
He would be the first African former president to hold such responsibility and would oversee UN affairs on the African continent.
The role is similar to that of former British Prime Minister, Tony Blair, who was appointed the Middle East envoy for the United Nations after leaving office.
Jonathan, 57, holds a B.Sc. in zoology, an M.Sc. in hydrobiology and fisheries and a Ph.D in zoology, all from the University of Port Harcourt.
Prior to his role as President, Jonathan served as governor of Bayelsa State from 2005 to 2007 and as Vice President of Nigeria from 2007 to 2010.
Meanwhile, a former Kogi State Governor, Abubakar Audu, has said that Jonathan deserves the Nobel Peace prize for his historic phone call to the President-elect, Muhammadu Buhari, in which he conceded defeat in the recent presidential elections.
In another development, Jonathan on Monday, commissioned the new Christian Association of Nigerian’s (CAN) Jubilee Resort and Leadership Centre in Abuja.
The centre, which is within the premises of the National Christian Centre, Abuja, provides rooms, accommodation and halls for conferences to the public at a fee.
Thanking God that he oversaw the project from inception to completion, Jonathan said that with unity of purpose, the body of Christ can achieve greater things.
“I urge Nigerians to imbibe the spirit of unity and with it nothing can stop us from reaching greater heights,” he said, adding that one of the greatest assets from a family to the nation is good leadership.
“I believe this centre will be used to re-orientate and re-focus us,” he said.
He warned that it would not be good if the edifice cannot generate income to at least cater for its maintenance.
Commending the prudence in the cost of the building, he said such building and its facilities would have cost three times the amount spent on it if it were handled by the government.
The President, Christian Association of Nigeria (CAN), Pastor Ayo Oritsejafor, said that the cost of the building was low because some engineers and other people gave their services free.
He said that although that there were many five-star and four-star hotels in Abuja, none provides a quiet and godly place like the resort, adding that the presence of God is worth more than any other thing.
