A solemn assembly is a God-ordained time of deep spiritual cleansing, repentance and restored first love. (Joel 2:12-18) Yet today, it is all too possible to attempt solemn assemblies that are shallow and over-programmed. When this occurs, churches experience a subtle form of “spiritual inoculation.” In essence, we can receive a weakened version that actually keeps us from the genuine return to God. It is also possible to conduct solemn assemblies in ways that are so brief and programmed, that the Holy Spirit has little freedom to guide believers into life-changing repentance. In this book, leaders receive effective guidance for experiencing a church-changing, Spirit-guiding encounter with God.
