Zac Poonen emphasizes Peter's journey of faith and his attitude towards money and correction, illustrating how God had a greater calling for Peter that required testing and approval. When Jesus called Peter to leave his fishing business, he chose to follow Christ instead of seeking material wealth, demonstrating a profound understanding of true riches in God's kingdom. Poonen contrasts Peter's response to wealth with the modern Christian mindset that often seeks prosperity and material gain, warning against the deception of earthly-mindedness. He highlights Peter's humility in accepting public rebuke from Jesus, showcasing that true discipleship involves embracing correction as a path to eternal life. Ultimately, Peter's choices reflect a commitment to spiritual wealth over earthly success.
