The statute was commissioned by Obinna Onuoha, a local businessman who hired a Chinese company to carve it. It was placed in the grounds of a 2000-capacity church that he built in 2012.
The cost of the statue has not been revealed.
The 43-year-old boss of an oil and gas service company timed the statue's unveiling to coincide with his parents' 50th wedding anniversary.
And when his 68-year-old mother fell seriously ill a few years ago, she made him promise that he would build a church if she survived.
