Failure is not final for the Christian, Jesus restores Peter and gives him responsibility and commisons him to strengthen his brethren. Years later Peter would do so as he writes to the suffering belivers in 1 Peter 1. He strengthens them by reminding them of the Greatness of God and the salvation thee in him .Peter was not a flawless man, but he was the Lord’s and we see Peter pointed to a Faithful Savior. Failure is not final and you can continue to point people to the Flawless Savior and the blessings that are theirs because of Him in time of suffering! Peter teaches them to Focus on His Greatness and Their great blessings as a result of the resurrection of Jesus for them! Failure is not fatal for the beliver. Focus on Him in times of pain.
