I never asserted that Paul, all at once, preached 1 Cor. 15:1-4 KJV-progressive revelation.
You deceitfully changed the subject/argument of yours-you assert that there is only one piece of good news in the book. You made that up, and thus, have to assert that Judas preached the good news of 1 Cor. 15:1-4, along with the 11, prior to the occurrence of the DBR. The 11 never preached the good news that "Christ will die for your sins...be buried...be raised for your justification...Believe it to be saved!!"at least prior to its occurrence. You can't show it.
On record-you assert that your saint Judas preached the good news of 1 Cor. 15:1-4 KJV. Satanic.
Now you are agreeing with me, that we do not need to hear the full message in one go in order to be saved. Believing on the Lord Jesus Christ will save us.
He therefore is the good news, from Genesis to Revelations.
I completely agree that Peter and the others did not preach or even understand the dbr until Pentecost. Nor did they even then understand it like what they should have done. But the dispensation was in place from the cross onwards.
Paul was given the fullest revelation of it and especially how it relates to the Gentiles. THAT we agree
