Mark made this call at a Special Mass at the Chapel of Testimony, Apo, Abuja, to mark his 67th birthday.
He said this prophecy led to exodus of Nigerians to their states of origin in fear of the violence predicted.
“On Election Day, people thought that the fight was going to be one that had never been seen in this country before, but God heard our prayers, the election came and went, no major incidents.
“Results were announced and President Goodluck Jonathan conceded defeat even before the final result and congratulated General Buhari.
“I think this is God’s way of telling Nigerians that he has put us together and we must remain one united country.
“Those who were predicting that this country will be gone should apologise to Nigerians; there were so many prophesy.
“The problem with all these prophets is that when things do not go their own way, they find another way of coming back and telling us that what they meant was this, they spoke in tongues and we did not understand.
“As a nation, we have risen beyond the wishes of all these prophets of doom, but what is more important is that we have established a firm root of democracy in this country’’, he said.
Mark expressed the hope that the Peoples Democratic Party (PDP), would win more seats than the All Progressives Congress (APC), in the governorship and State Houses of Assembly elections.
The Leader of the Senate, Victor Ndoma-Egba, said that the loss of the PDP was the gain of Nigeria.
He said while the prophets were prophesying doom, God was working to ensure that Nigeria remained as one.
“Up to a few days ago, we heard drums of war, doomsday prophets were at work and they were very busy saying that Nigeria was going to break-up.
“They did not realise that God fixed the elections during the holiest period in Christianity – the Lent period – for a purpose.
“We had the elections and God did it for Nigeria and for Nigerians, but God also used people to achieve this.
“When the story is told, when the history is written, the role of Sen. David Mark will be properly documented”, he said.
He congratulated Mark for the role he played in Nigeria’s survival of the election period, reiterating that “PDP’s loss is Nigeria’s gain.”
