He said although Ghanaians would be casting their ballot on December 7, God is the one who crowns Kings.
With some eight days to the presidential and parliamentary elections, the two dominant parties; the governing NDC and New Patriotic Party (NPP) are rounding up their campaigns.
President Mahama and his opponent NPP's Nana Addo Dankwa Akufo-Addo have focused their campaign activities in regions considered swing regions.
The three regions are the Western, Greater Accra and Central Regions.
The two leaders are currently on the homestretch in the Central Region campaigning miles away from the other to garner the electorate's vote.
Joy News’ Richard Kwadwo Nyarko reported that Mr Akufo-Addo took his campaign activities to the Upper Denkyira East Constituency while President Mahama was in Upper Denkyira West Constituency.
Three out of four opinion polls conducted by some reseach institutions have predicted a resounding victory for the NPP leader. London-based Economic Intelligence Unit (EIU) has said Mr Akufo-Addo would win the election in the two polls it conducted in Ghana.
Political Scientists at the University of Ghana Politcal Science Department have also said the NPP leader would win the election.
However, in his first poll in ahead of the polls, renowned Ghanaian pollster, Ben Ephson has said President Mahama would win by 52.4 percentage point against Mr Akufo-Addo's 45.9 percent.
The other presidential candidates; Progressive People's Party (PPP)'s Dr Papa Kwesi Nduom, National Democratic Party (NDP)'s Nana Konadu Agyemang-Rawlings, Convention People's Party (CPP), Ivor Kobina Greenstreet, People's National Convention (PNC)'s Dr Edward Mahama and an independent candidate, Jacob Osei Yeboah would settled with 1.7 percent.
But President Mahama expressed confidence in amassing more than the 52.4 percent predicted by Mr Ephson.
He charged resident of Central Region to help him get more than 55 to 60 percent of the votes so that he would not be dragged to court as happened in 2012 when the NPP challenged his victory at the Supreme Court.
'God has given me the mandate. Let's vote well so that it would be more so that no one would go to the court,' he said.
