God's plan for changing the world centers on the local church, which Jesus promised would prevail against the gates of hell. Christians are called to be salt and light, preserving culture and illuminating darkness through courageous action. Fear, however, often paralyzes the church as it did the Israelites at the edge of the Promised Land. A courageous church preaches the whole Bible, confronts spiritual darkness, challenges people to change, and speaks truth when culture demands silence. This courage manifests personally when we stay in difficult situations, speak truth at personal cost, live by God's wisdom, and help those who cannot reciprocate.
