Zac Poonen emphasizes that the Christian life is a race towards becoming more like Jesus, highlighting the importance of moving beyond just being saved to actively pursuing spiritual growth. He explains that while many Christians are content with their salvation, they must strive to win God's approval by embodying Christ-like qualities and making choices that reflect their faith. Poonen illustrates this through the life of Moses, who, despite his mistakes, demonstrated a passion for knowing God and a commitment to His ways. He encourages believers to seek a deeper relationship with God, emphasizing that true eternal life is about knowing Him more intimately. Ultimately, Poonen calls for a balance between understanding salvation and actively running the race of faith.
