What did Paul make a big deal about regarding his relationship to the resurrected Christ?

Paul made a big deal that he had personally seen and heard the resurrected Christ and received these things from Him. His message centered on the crucified, buried, risen Lord now ascended to glory, preaching Christ crucified and the work of the cross.

Les explains that Paul made a big deal over having seen and heard these things from the resurrected Christ because his message was not the pre-cross ministry of the Gospels. Les points out that the Gospels record Christ before the work of the cross, before the atoning blood was shed, and under the Law, in accordance with the Judaic legal system, with nothing of the Gospel of Grace. Peter carried that early ministry into Acts. But Paul, by contrast, talks only about the crucified, buried, and risen Lord, now ascended to glory. Les also notes that the little Jewish epistles—James, 1 and 2 Peter, 1 and 2 John, Jude, and Revelation—do not even mention the word cross, because for them it was not the pinnacle of information as it was with Paul. Paul says we preach Christ crucified, and all he knows is the work of the cross.

What did the Apostle Paul make such a big deal about in his ministry?

The Apostle Paul made much of having seen and heard the resurrected Christ and of preaching Christ crucified, buried, risen, and ascended. His ministry centered on the work of the cross, which he said was the pinnacle of information, unlike the pre-cross Gospels and Jewish epistles.
