More than any other who was called by Jesus, Peter knew what it was like to fail and fall. If there was one man who might give up following Jesus, Peter would have been the one.
When Jesus asked who the disciples thought that He was, Peter did not hesitate to say, “You are the Christ, the Son of the Living God.”
Jesus commended Peter for his insight, telling him that the Father had revealed this to Him.
Then when Jesus said that He would be arrested, scourged, and crucified, Peter said, “Far be it from You, Lord; this shall not happen to You!” But Jesus turned and said to Peter, “Get behind Me, Satan! You are an offense to Me, for you are not mindful of the things of God, but the things of men.”
Impetuous, impulsive, often directed by his flesh rather than the Spirit, Jesus still wanted Peter to lead the other disciples in telling the world about Him. After Jesus had risen from the dead and He sent the Holy Spirit to fill and live in all of those who believed in Him, Peter was a different man. The books of 1 and second Peter are filled with insight and experience that Peter learned through his failures and the patience of Jesus.
