"But in fact, Christ has been raised from the dead. . . "
All that was said yesterday becomes a non-issue in the light of the FACT of the resurrection. This is why Paul begins the section saying these are the things of first importance. That Christ died, was buried and raised on the third day FOR OUR SINS, just as the Scripture said. Note it wasn't just the fact of the death burial and resurrection of Christ but the reason too. FOR OUR SINS. As he says later in verse 17, "If Christ has not been raised, then your faith is useless and you are still guilty of your sins." But the truth is He has been resurrected. Paul includes a list of all those who saw Him post-resurrection. Clearly there were skeptics in Paul's day too.
Dr. Frank Morrison (a rationalistic lawyer) took three years off from his practice to apply his legal skills to see if the evidence for the resurrection would stand up in a court of law. As a result he wrote the book Who Moved the Stone? Morrison's book is considered by many to be a classic apologetic on the subject of the Resurrection, and he himself ceased to be a rationalist. The evidence is compelling. Here is a summary of Morison's conclusions.
1: The Prophets Spoke of it in the Old Testament
2: Jesus Foretold it in the New Testament
3: The Historical Record Implies It
4: The Empty Tomb Provides Us With Evidence
5: The Many Post-Resurrection Appearances (15)
6: It Changed Their Lives

There is no historic incident better or more variously supported than the resurrection of Christ. Brooke Foss Wescott
No shred of evidence has yet been discovered in literary sources, epigraphy or archaeology that would disprove that the tomb in which Jesus was buried was actually empty on the morning of the 1st Easter. Dr. Paul L. Maier (professor of ancient history)
According to the laws of legal evidence used in courts of law, there is more evidence for the historical fact of the resurrection of Jesus Christ than for just about any other event in history. Dr. Simon Greenleaf (a Harvard University professor of Law)
