Jesus the apostle prophet spoke the words of the father our lord who yields power to forgive and rebuke the spirit of lies. (legion) .Jesus as the Son of man had no power. Jesus as the Son of man, he is considered a angel as all true apostles. (sent ones)
The man of sin, Satan is the antichrist who works in many or a legion of those led by the spirit of the antichrist (one) . The false apostle false prophet .
It would appear he produced false pride in Peters heart moving Peter to rebuke the Son of man. Peter in false pride trying to make the gospel key that the gates of hell could not prevail against to no effect . . giving it to Peter who "blasphemed" Christ working in the Son of man, Jesus.
The Father put his words on His apostles lips (Jesus) and God rebuked the father of lies. And the same Spirit not seen forgave Peter of his blasphemy.
The Lord saying to the father of lies "the legion" .get behind me . . God, not seen. Walk by faith rather than getting behind supporting Peter a man of sin living in a corrupted body of death , and support me as you were created to do .
An eternity of difference between corrupted dying mankind the temporal seen and our father not seen. They must be mixed called the mixing of faith(the gospel) the temporal seen points to the eternal not seen . Hebrews 4:1-2 our daily sabbath .
The letter of the law must be mixed with the law of faith .It as one new perfect law. It produces the just and the justifier apart from each other no grace. .One God working as two .The father taking the greater position with power to strengthen the powerless creature the Son of man Jesus. . Yoked with Christ our daily burden is made lighter.
Mathew 16: 21-23 From that time forth began Jesus to shew 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 thee, Lord: this shall not be unto thee. But he turned, and said unto Peter, Get thee behind me, Satan: thou art an offence unto me: for thou savourest not the things that be of God, but those that be of men.
