The Apostle Peter was the oldest of the disciples.  He was not an ignorant fisherman.  He could read and speak four-languages; he ran a small business; he was an accomplished speaker; and he wrote two of the letters in the New Testament.  Unlike the other disciples, Peter knew that he was not good enough.  Peter constantly failed, yet our Lord in his mercy restored Peter each time.  Peter’s testimony of the Gospel emphasizes not only God’s grace but also God’s mercy, in not giving Peter what he deserved.
