Moody Adams, 'Proof' A change took place after the death of Jesus that changed Peter into a man who no longer feared death. Before this time he rebuked Jesus for saying He would be raised from the dead. When he felt his life was in danger for being associated with Jesus, Peter cursed vehemently and swore he did not know Christ, moments before Jesusí final agony.
Prior to this, when Jesus told Peter He would rise, Peter refused to believe it: From that time forth began Jesus to show unto his disciples, how that he must go unto Jerusalem, and suffer many things of the elders and chief priests and scribes, and be killed, and be raised again the third day: Then Peter took him, and began to rebuke him, saying, Be it far from you, Lord: this shall not be unto thee. But he turned, and said unto Peter, Get you behind me, Satan: you are an offence unto me: for you savorest not the things that be of God, but those that be of men (Matthew 16:21-23).
After the crucifixion Peter left and went back to fishing on the Sea of Galilee. But then Peter saw the risen Christ and his life was immediately changed.
Peter came crashing into Jerusalem to announce he had seen a resurrected Jesus; Therefore being a prophet, and knowing that God had sworn with an oath to him, that of the fruit of his loins, according to the flesh, he would raise up Christ to sit on his throne; He seeing this before spoke of the resurrection of Christ, that his soul was not left in hell, neither his flesh did see corruption. This Jesus hath God raised up, whereof we all are witnesses (Acts 2:30-32). Again Peter testified . . . the Prince of life, whom God hath raised from the dead; whereof we are witnesses (Acts 3:15).
Seeing the risen Christ erased all of Peterís doubt: For we have not followed cunningly devised fables, when we made known unto you the power and coming of our Lord Jesus Christ, but were eyewitnesses of his majesty (II Peter 1:16).
The man who had feared death so much he would curse and swear he did not know Christ, no longer feared death: Knowing that shortly I must put off this my tabernacle even as my Lord Jesus Christ has showed me (II Peter 1:14). But this did not shake Peter. He is said to have declared he was not worthy to die like his Savior. So the men who crucified him turned him upside down.
