[Ali Imran]

”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. And he spake that saying openly. And Peter took him, and began to rebuke him. 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.“
‭‭Mark‬ ‭8‬:‭31‬-‭33‬ ‭KJV‬‬

Think about it. If Jesus had said that to the disciples, why would the disciples take the news of the risen Jesus as ridiculous? Wouldn't they be expecting it at the very least? We cannot find the answer to that mystery. So, I will mark that verse as suspicious because it doesn't fit the story. Also, the sign of Jonah. If Jesus had said that, why the disciples wasn't expecting Jesus to rise again after they thought he had died? On top of that, in one Gospel, Jesus said "No sign will be given" and he walked away. In another, Jesus gave a sign, the sign of Jonah. The 2 Gospels contradict each other so which one is true?

Even so, Jesus didn't say he would die for your sins. He just said he would be killed.
