'The Twelve' disciples did not know that Jesus was going to be nailed to a cross. So how could the disciples have been preaching Paul's Gospel?:
31- Then he (Jesus) took unto him the twelve, and said unto them, Behold, we go up to Je-ru'sa-lem, and all things that are written by the prophets concerning the Son of man shall be accomplished.
32- For he shall be delivered unto the Gentiles, and shall be mocked, and spitefully entreated, and spitted on:
33- And they shall scourge him, and put him to death: and the third day he shall rise again.
34- And they (the disciples) understood none of these things: and this saying was hid from them, neither knew they the things that were spoken.
-Luke 18 v 31-34
Many times Jesus told his disciples the same thing and nothing came of it*. The scriptures continue and nothing was made of such a profound statement by Jesus Christ. The disciples spoke not a word in protest or of understanding. What Jesus told them went right over their heads. Beaten! Scourged! Crucified! Murdered! Resurrect! It was by divine plan that Jesus Christ would fulfill the prophecies of Israel. His beloved disciples where not going to interfere. *-Matthew 16 v 21-23; -Matthew 17 v 22, 23; -Matthew 20 v 18, 19; -Matthew 26 v 1, 2, 45, 46, 52-56; -Mark 8 v 31-33; -Mark 9 v 31, 32; -Mark 10 v 33, 34, 45; -Luke 9 v 22
'The Word of God' said it, it is undeniable. The disciples did not know that Jesus was going to the cross to be crucified, though Jesus told them. Nor did 'the Twelve' disciples know he was going to resurrect three days later and Jesus told them that as well. Had they known he was going to resurrect from death, wouldn't they have been camped outside the sepulcher waiting for Jesus to appear? Or at least in 'hidden eyesight' of the tomb? None of them did. Hello!?
1- The first day of the week cometh Mary Magdalene early, when it was yet dark, unto the sepulcher, and seeth the stone taken away from the sepulcher.
2- Then she runneth, and cometh to Simon Peter, and to the other disciple (John), and saith unto them, They have taken away the Lord out of the sepulcher, and we know not where they have laid him.
3- Peter therefore went forth, and that other disciple, and came to the sepulcher.
4- So they ran both together: and the other disciple did outrun Peter, and came first to the sepulcher.
5- And he stooping down, and looking in, saw the linen clothes lying; yet went not in.
6- Then cometh Simon Peter following him, and went in to the sepulcher, and seeth the linen clothes lie.
7- And the napkin, that was about his head, not lying with the linen clothes, but wrapped together in a place by itself.
8- Then went in also that other disciple (John), which came first to the sepulcher, and he saw, and believed.
9- For as yet they knew not the scripture, that he must rise again from the dead.
-John 20 v 1-9
After Peter and John saw the burial clothes folded and Jesus not there in the sepulcher, then they believed. Jesus was missing and not where he had been laid, dead. A prudent grave robber wouldn't take the time to fold his burial clothes before stealing the body. Besides, there were Roman soldiers guarding the sepulcher to ensure that such a thing would not happen.
Their understanding of what Jesus had told them (uttered) now was understood. “For as yet they knew not the scripture, that he must rise again from the dead”. Call man and me a liar but call the 'Word of God' a liar….? Read it, believe it for yourself. Take no person's 'supposed head knowledge' in place of the 'Word of God'.
