Following Pentecost and the arrival of the Holy Spirit's permanent indwelling of believers, we see the dynamic Body of Christ at work. The early church was dynamic for several reasons, including: 1) generosity and sacrificing for others needs; 2) having a corporate unity of heart and mind; 3) interacting in both small and large groups, where large groups were dynamic and exciting and small groups allowed for deep intimacy and relational involvement; 4) authentic community that was sincere about the time spent with one another; 5) active gratitude, praising God regularly; 6) integrated with the culture around them; and 7) outreaching to others with the message of Jesus' forgiveness. These qualities have disappeared throughout the majority of the Western Church because of materialism and different priorities. This type of ethos within the church is powerful in demonstrating God's power and love to others.
