Chuck Smith emphasizes that the Christian life is meant to be full, rich, and abundant, despite the battles we face. He explains that entering the promised land symbolizes a life of continual joy and victory, not the absence of struggles. Smith outlines the principles of conquest, urging believers to let God lead and to obey His voice, rather than rushing into battles on their own. He also highlights God's method of conquest as 'little by little,' revealing areas for victory gradually to ensure we depend on Him. Ultimately, the sermon encourages Christians to trust in God's perfect strategy and timing for their lives.
