Kingdom Come represents God's dominion manifesting on earth through believers who embrace His purposes. It operates through both power - catching God's wave, and authority - starting the wave. To grow in kingdom authority, believers must prioritize God's presence, cultivate worship, pursue discipleship, and build authentic community. Overcoming obstacles like religious formality and comfort zones is essential for demonstrating God's authority in daily life. This authority comes not from personal achievement but through Christ's finished work on the cross.
