Prophet Nakoa Nazareth Ansah Jamson, Spiritual Leader of the Prophets and Spiritual Churches Council in Ghana, has described corruption as a bad wind which is blowing in the country.
He gave the assurance that it would soon come to an end, since Ghana is God chosen country.
Prophet Nakoa Jamson made the remark in an interview with newsmen when the Prophets and Spiritual Churches Council organized a national thanksgiving service and prayers for the country at the Independence Square in Accra.
The service was to thank God for the peace, before, during and after the Supreme Court verdict on August 29, 2013.
Prophet Nakoa Jamson said God has been merciful to the country during the 2012 election and therefore He deserved praise and adoration from Ghanaians.
“The peace and tranquility that followed the court verdict is phenomenal and must be acknowledged with thanks to our God Jehovah most High.”
