I am writing tonight from the beautiful Tampa Bay area.
Mark 8 :29 And he saith unto them, But whom say ye that I am? And Peter answereth and saith unto him, Thou art the Christ.
8:30 And he charged them that they should tell no man of him.
8:31 And he began to teach them, that the Son of man must suffer many things, and be rejected of the elders, and [of] the chief priests, and scribes, and be killed, and after three days rise again.
8:32 And he spake that saying openly. And Peter took him, and began to rebuke him.
8:33 But when he had turned about and looked on his disciples, he rebuked Peter, saying, Get thee behind me, Satan: for thou savourest not the things that be of God, but the things that be of men.
8:34 And when he had called the people [unto him] with his disciples also, he said unto them, Whosoever will come after me, let him deny himself, and take up his cross, and follow me.
8:35 For whosoever will save his life shall lose it; but whosoever shall lose his life for my sake and the gospel’s, the same shall save it.
8:36 For what shall it profit a man, if he shall gain the whole world, and lose his own soul?
8:37 Or what shall a man give in exchange for his soul?
8:38 Whosoever therefore shall be ashamed of me and of my words in this adulterous and sinful generation; of him also shall the Son of man be ashamed, when he cometh in the glory of his Father with the holy angels.
Peter could not comprehend or imagine Jesus being crucified. I think this is why Peter was so sure of himself, when later he swore he would never deny Jesus. I think he made that promise while only thinking of Jesus upon a throne, never dreaming Jesus would be crucified on a cross. Jesus rebuked Peter, because Peter was telling Him he did not need to die to self on the cross. Jesus at once recognized this as a message from Satan. Earlier Satan had told Jesus He would not have to die if He would just worship him. If he would, then Satan would give Jesus the world back without Him needing to die. Long before this, Satan spoke through false prophets in the Old Testament, prophesying smooth things that kings longed to hear. The kings would get upset when a real prophet would prophesy about death and destruction, because they did not want to hear it. Peter did not want to hear it either. Peter only wanted smooth things prophesied to him. Jesus, the King of Kings had to overcome where the former kings failed, and be willing to accept a prophecy of death and loss. Jesus gives Peter a further rebuke, when he tells him that if he is ashamed of these words about the cross, then Jesus would also be ashamed of Him when He comes in glory. Peter, who at the time could only imagine a throne and glory, finally found that glory-in the cross. He who loses his life finds it. Jesus was glorified after he was crucified. Do you want glory and honor and a throne too? Then pick up your cross and follow Jesus in death to self. Find the glory that many Old Testament kings greatly desired, but were never willing to die to self for.
