“Moreover, brethren, I declare to you the gospel which I preached to you, which also you received and in which you stand, by which also you are saved, if you hold fast that word which I preached to you—unless you believed in vain.”1 Corinthians 15:1-2
It is fun to ask that question of one who you know does not believe in the Resurrection of Jesus Christ. One may answer in bluntness: “Well I just do not believe it!” When you pursue the subject, get ready for a trip around the world ending up where you started, without a logical answer; especially when you give the recorded words of Paul the Apostle in 1 Corinthians 15.
Paul, in enumerating why he believed in the resurrection, provides his satisfaction with the resurrection because of numerous appearances of Christ, after his body had been placed in a sealed tomb. Christ appeared to Cephas (Peter), to the twelve, five hundred at one time, James, to all the apostles, and last of all, to me also. (Paul) Obviously, some individuals would not be moved to address those facts as certain. They would probably wave their arms and move on. In actuality, there were others who observed the resurrected Savior, though Paul does not attempt to list all the appearances of Christ at once.
It is beyond argument as far as Paul is concerned. He recalls that moment on the Damascus Road when he was struck to the ground, blinded, and heard the voice of the Savior himself, “I am Jesus whom you persecuted!” From the persecutor to the persecuted! While we may question the origin of a person’s experience, we cannot deny the experience itself. To be certain that Paul knew who he was hearing, our Lord identifies Himself: “I am Jesus whom you persecuted.” (Acts 9)
That confirmation by the Savior Himself vouched His Personage, leaving the man who continued on to Damascus. He had his sight restored by the Lord through the ministry of Ananias, became the evangelist of evangelists, and opened the world of his day and ours to the gospel of the Resurrected Christ.
And would anyone question that Christ arose? By the way, I write this in 2019 Anno Domini! (The year of our Lord.)
