Recent issues
Stephen Tong has preached the Gospel to 1,5 million Indonesians in 2012. According to the International Evangelism Fellowship's adaptation of the press release by the Indonesian Evangelical Reformed Church till November 2012 the Reformed Evangelical Church's sermons have reached 1,5 millions. 700 preaching assemblies that was led by Stephen Tong were held. In October 200,000 people were able to hear the Gospel. The church reaped great evangelisation work in 2012. Indonesia is populated by about 250 million people, in which the majority are muslims. Thus, evangelisation there is a long process. As Pastor Tong noted, if the GRII preaches to 1 million people per year it would take 218 years for all Indonesians to hear the Gospel. Therefore, he urged the church to not be proud of its accomplishments, because there is great distance towards the evangelisation of the entire country. In a four-days evangelistic outreach in December 2012 Tong preached in the Messiah Cathedral in Jakarta to 30,000 attenders. On December 28, 2019 at the National Reformed Evangelical Convention, an annually held convention in Indonesia, Pastor Tong brought up an issue that the church was currently experiencing: a crisis of male servants to serve as sunday school teachers and a vacant of fatherly authority in children's life because Sunday school teachers are predominantly women. He called for the young generation, especially men, to surrender themselves as servants of God to serve as sunday school teachers in their respective churches.
