In 1989, Kong felt the call of God to enter into full-time Christian service. Kong had, by then, graduated with a degree in Computer Science from the National University of Singapore and was working for a publishing house. Having held several small, but successful, evangelistic campaigns in Singapore, Malaysia and the Philippines, Kong wanted to become an itinerant evangelist to assist the churches in Southeast Asia. In April that year, he left the Anglican Church he was attending since he was a child and set out to become a staff evangelist with “Christ for Asia,” a Singapore-based mission’s organization. In 2001, CHC built a 2,300-seater, titanium-clad church complex in Jurong West Street 91 for S$48,000,000. Apart from that, it has offices and schools in three different locations. City Harvest Church (CHC) has 47 affiliate “Harvest” churches in 2010. City Harvest Church (CHC) has direct supervision over 29 of them, while 18 come under the oversight of Harvest School of Ministry led by Rev. George Ong. Mission statement of City Harvest Church is “To build a church with a strong spiritual atmosphere of faith and purity, where every member is released into ministry, disciple in the Great Commandment to obey the Great Commission and the Cultural Mandate”. The Church officially bases its values on Charismatic and Pentecostal teachings, with emphases on such “doctrines” as “the Great Commandment”, “the Great Commission” and “the Cultural Mandate”. The primary church building is located at Jurong West Street 91, and was completed in 2002. Its construction was part of a trend of larger churches in Singapore to go for “clean lines, stainless steel, titanium facades” for their architecture in place of “stained glass and steeples” in an effort modernize their religious services. The building occupies almost 38,000 sq ft (3,500 m2) on a 30-year leasehold land and its main hall seats up to 2,300 attendees and has two 250-seat halls. Since 19 March 2011, CHC has moved to the Suntec International Convention and Exhibition Centre.
