Not only is he a competent representative of Jesus to us, Peter is also representative of each one of us in the vulnerability of our sinfulness and frail humanity. We are creatures of fluctuation - from faith and fortitude to fear and folly. Deep down Peter the disciple is typical of every disciple of the Lord Jesus and that is why we find him to be such an agreeable spiritual companion. Human impulse and divine influence vied within him until he was shaped into the pastor and preacher God intended him to be. Our gravest faults, in God’s mercy, encounter great grace.
