The Hot Church: Stories, Faith & Fellowship Pastor Chae explores what it means to be a spiritually vibrant, passionate, and "hot" church—referencing the spiritual temperature described in Revelation 3:15-16, where believers are challenged to be neither cold nor lukewarm. Pastor Chae addresses how cultural trends, cynicism, and routine can cause a church or individual believers to drift into spiritual apathy. He contrasts a passive, lukewarm faith with a community energized by the Holy Spirit.
