What difference would it make if the Resurrection of Christ never really happened?

“How do some among you say that there is no resurrection of the dead?” (1 Cor. 15:12). The Corinthian Christians believed in Christ’s resurrection, or else they could not have been Christians (John 6:44; 11:25; Acts 4:12; 2 Cor. 4:14; 1 Thess. 4:16). But some had particular difficulty accepting and understanding the resurrection of believers. Some of this confusion was a result of their experiences with pagan philosophies and religions. A basic tenet of much of ancient Greek philosophy was dualism, which taught that everything physical was intrinsically evil; so the idea of a resurrected body was repulsive and disgusting (Acts 17:32). In addition, perhaps some Jews in the Corinthian church formerly may have been influenced by the Sadducees, who did not believe in the resurrection even though it is taught in the Old Testament (Job 19:26; Pss. 16:8–11; 17:15; Dan. 12:2). On the other hand, New Testament teaching in the words of our Lord Himself was extensive on the resurrection (John 5:28, 29; 6:44; 11:25; 14:19), and it was the theme of the apostolic preaching (Acts 4:1, 2). In spite of that clarity, the church at Corinth was in doubt about the resurrection.

In vv. 13–19, Paul gives 6 disastrous consequences if there were no resurrection: 1) preaching Christ would be senseless (v. 14); 2) faith in Christ would be useless (v. 14); 3) all the witnesses and preachers of the resurrection would be liars (v. 15); 4) no one would be redeemed from sin (v. 17); 5) all former believers would have perished (v. 18); and 6) Christians would be the most pitiable people on earth (v. 19).
