1.The 12 did not know of the impending dbr-it was hid from them, until later in the Lord's ministry-and yet, prior to them knowing, they were preaching "the gospel of the kingdom:"
"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. But they understood not that saying, and were afraid to ask him." Mark 9:31-32 KJV
"Then he took unto him the twelve, and said unto them, Behold, we go up to Jerusalem, and all things that are written by the prophets concerning the Son of man shall be accomplished. For he shall be delivered unto the Gentiles, and shall be mocked, and spitefully entreated, and spitted on: And they shall scourge him, and put him to death: and the third day he shall rise again. And they understood none of these things: and this saying was hid from them, neither knew they the things which were spoken." Luke 18:31-34 KJV
"For as yet they knew not the scripture, that he must rise again from the dead." John 20:9 KJV
2. Peter tried to prevent the Lord Jesus Christ's death, and His death was a key component of 1 Cor. 15:1-4, by which we are reconciled:
"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" Mt. 16:21-22 KJV
"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." Mark 8:31-32 KJV
3. Even after the Lord's death, burial, and resurrection, the 12 initially did not believe it:
"And when they saw him, they worshipped him: but some doubted." Mt. 28:17 KJV
"And they, when they had heard that he was alive, and had been seen of her, believed not. After that he appeared in another form unto two of them, as they walked, and went into the country. And they went and told it unto the residue: neither believed they them. Afterward he appeared unto the eleven as they sat at meat, and upbraided them with their unbelief and hardness of heart, because they believed not them which had seen him after he was risen." Mark 16:11 KJV
"And returned from the sepulchre, and told all these things unto the eleven, and to all the rest. It was Mary Magdalene and Joanna, and Mary the mother of James, and other women that were with them, which told these things unto the apostles. And their words seemed to them as idle tales, and they believed them not." Luke 24:9-11 KJV
" And while they yet believed not for joy, and wondered, he said unto them, Have ye here any meat?" Luke 24:41 KJV
Therefore, they were not preaching the dbr, "the gospel" of 1 Cor. 15:1-4 KJV, as a basis of justification, at least prior to its occurrence, but they were preaching the gospel of the kingdom. Therefore, they are not the same "the" gospels, "good news." This "argument" that there is just one "the gospel," just one piece of good news, self-destructs, "commits suicide". There is plenty of "good news"(and bad news) in the book-the context tells us what "good news"/gospel is in view.
