Rev. Jeffrey Cheng was born in Hong Kong. As a graduate of the University of Hong Kong, Jeffrey held a bachelor’s degree in actuarial science. He had worked as an actuary for 14 years, with an expertise in asset-liability management. Just like matching negative cashflow with a positive one, salvation from Jesus is the only way to repay the debt of sins- according to the Bible. Having moved by the Holy Spirit, Jeffrey accepted Jesus as his Saviour in the third year of his actuarial career.

Jeffrey earned his first master’s degree (Master of Christian Studies) from the Evangel Seminary in Hong Kong after 12 years following Christ. In 2014, God called the family to serve among the Chinese communities in the America. The family responded to the call, and in 2019, Jeffrey received his MDiv (Master of Divinity) from the Trinity Evangelical Divinity School in IL.

In 2020, the family started their ministry as church planters in Staten Island, NY. They began the Charis Community Church of C&MA, which was a Cantonese ministry during the COVID-19 pandemic. In 2023, God called Jeffrey to transition to a leadership and pastoral role at New Life Chinese Church in New Jersey.

Jeffrey loves to spend time with his family. He and his supportive wife, Jessica, have been married for many years. They have a gifted daughter and an intelligent son.
