Did the 12 understand the purpose of the Cross?

Lets see if the 12 understood what Jesus was going to do, shall we?

PETER AND PAUL DID NOT
PREACH THE SAME MESSAGE

Romans 16:25-26
Now to him that is of power to stablish you according to my gospel, and the preaching of Jesus Christ, according to the revelation of the mystery, which was kept secret since the world began, 26 But now is made manifest, and by the scriptures of the prophets, according to the commandment of the everlasting God, made known to all nations for the obedience of faith:

PETER from the first believed in the Lord Jesus Christ BUT understood nothing of the cross

Matthew 16:16-22 And Simon Peter answered and said, Thou art the Christ, the Son of the living God. 17 And Jesus answered and said unto him, Blessed art thou, Simon Barjona: for flesh and blood hath not revealed it unto thee, but my Father which is in heaven. 18 And I say also unto thee, That thou art Peter, and upon this rock I will build my church; and the gates of hell shall not prevail against it. 19 And I will give unto thee the keys of the kingdom of heaven: and whatsoever thou shalt bind on earth shall be bound in heaven: and whatsoever thou shalt loose on earth shall be loosed in heaven. 20 Then charged he his disciples that they should tell no man that he was Jesus the Christ. 21 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. 22 Then Peter took him, and began to rebuke him, saying, Be it far from thee, Lord: this shall not be unto thee.

Matthew 17:22-23 And while they abode in Galilee, Jesus said unto them, The Son of man shall be betrayed into the hands of men: 23 And they shall kill him, and the third day he shall be raised again. And they were exceeding sorry.

Mark 9:31-32
31 For he taught his disciples, and said unto them, The Son of man is delivered into the hands of men, and they shall kill him; and after that he is killed, he shall rise the third day. 32 But they understood not that saying, and were afraid to ask him.

Luke 9:43-45 And they were all amazed at the mighty power of God. But while they wondered every one at all things which Jesus did, he said unto his disciples, 44 Let these sayings sink down into your ears: for the Son of man shall be delivered into the hands of men. 45 But they understood not this saying, and it was hid from them, that they perceived it not: and they feared to ask him of that saying.

John 20:9 For as yet they knew not the scripture, that he must rise again from the dead.

PAUL had been a blasphemer BUT he was the last to see Christ and first to know of the mystery

1 Corinthians 15:8 And last of all he was seen of me also, as of one born out of due time. 1 Timothy 1:16 Howbeit for this cause I obtained mercy, that in me first Jesus Christ might shew forth all longsuffering, for a pattern to them which should hereafter believe on him to life everlasting.
