How was Peter prepared by God to strengthen his brethren?

Peter's preparation to strengthen his brethren is intricately tied to his personal experiences and the sovereignty of God in his life. First, Peter was a direct witness to the life, death, and resurrection of Christ, which equipped him with firsthand knowledge to share with others. Additionally, his journey included moments of downfall and restoration, teaching him humility and reinforcing the necessity of relying on divine strength. The Lord preserved Peter's life during trials, such as his imprisonment, enabling him to minister effectively to others later. Furthermore, his vital roles during significant events, such as Pentecost and the outreach to the Gentiles, provided him with divine authority and experience that prepared him for the ministry of strengthening the church, illustrating how God uses our struggles and experiences for the growth of His kingdom.
