When God ignites a revival fire, it's unmistakable and transformative. The early church in Acts 2 demonstrated how to sustain this divine flame through four key practices within small groups: continuing steadfastly in doctrine (deep biblical teaching), fellowship (authentic community), breaking of bread (communion), and prayers (corporate intercession). These practices weren't complicated but proved profoundly effective. Small groups create environments where believers can go deeper than what's possible in large gatherings, helping the fire spread from person to person. The revival that began at Pentecost continued because believers committed to these practices, showing us that sustaining spiritual fire requires intentional connection and commitment.
