Are you trying to say that the disciples went around preaching the death, burial and resurrection of Jesus Christ for sins even though they were clueless about it?
In the Mark 8 account, Peter even rebukes Jesus for speaking such words:
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.32 And he spake that saying openly. And Peter took him, and began to rebuke him.
Can you imagine Peter rebuking the Lord for the sake of our gospel?
