The kingdom of God is not a political movement or social reform - it's a spiritual reality that begins within believers when they're born again. As citizens of God's kingdom, Christians are called to build it through prayer and sharing the gospel, not through earthly systems or legislation. Jesus gave us both the unchanging message of repentance and forgiveness through His death and resurrection, and the clear method of making disciples by going, preaching, baptizing, and teaching. Every believer has the responsibility to actively share their faith with family, friends, neighbors, and everyone they encounter. Building God's kingdom means changing hearts through the gospel, not changing laws through politics.
