THE CHURCH OF THE REVIVAL OF THE WORD OF GOD (GKKA) INDONESIA is a Protestant Christian church synod in Indonesia that adheres to the Reformed Evangelical Church denomination.
GKKA was born from the ministry of the Chinese Foreign Missionary Union (CFMU) Mission Agency, which began operating in 1928. GKKA Indonesia was established on May 12, 1973. GKKA-I Palu was established on August 2, 1998.

To address the challenges of the modern technological age for the church, the church created a church application with the primary goal of increasing congregational engagement, expanding outreach, and facilitating communication and church ministry. This application provides various features that make it easier for congregations to access information, participate in church activities, and connect with the church community, even when they cannot physically attend.
