Did He have to rise from the dead?

The short answer Settled

Yes. If Christ had not risen, believers would still be in their sins. His rising is part of what saves, not only a sign that His death had worked. And He rose in the body that died: the risen Jesus had flesh and bones and bore the wounds of the cross.

Still in your sins

Some in Corinth were saying "that there is no resurrection of the dead" (1 Corinthians 15:12). Paul's readers had already received "that Christ died for our sins according to the Scriptures" (1 Corinthians 15:3). Even so, he tells them what would follow if Christ had not risen: "And if Christ is not risen, your faith is futile; you are still in your sins! Then also those who have fallen asleep in Christ have perished" (1 Corinthians 15:17-18).

A Christ who died for sins and stayed dead would leave every believer unforgiven, not merely unsure.

Saved by His life

Peter says God "has begotten us again to a living hope through the resurrection of Jesus Christ from the dead" (1 Peter 1:3). The new birth comes through the resurrection.

Paul sets the death and the life side by side: "if when we were enemies we were reconciled to God through the death of His Son, much more, having been reconciled, we shall be saved by His life" (Romans 5:10). His death reconciled enemies. His life saves those who have been reconciled. Jesus said it simply: "Because I live, you will live also" (John 14:19).

Flesh and bones

When the risen Jesus stood among His disciples, "they were terrified and frightened, and supposed they had seen a spirit" (Luke 24:37). He answered, "Behold My hands and My feet, that it is I Myself. Handle Me and see, for a spirit does not have flesh and bones as you see I have" (Luke 24:39). Then He asked for something to eat, "And He took it and ate in their presence" (Luke 24:43). A ghost does not ask for a piece of fish.

To Thomas He said, "Reach your finger here, and look at My hands; and reach your hand here, and put it into My side" (John 20:27). The wounds show that the risen body is the body that was crucified.

Jesus had said so beforehand: "Destroy this temple, and in three days I will raise it up" (John 2:19). John explains, "He was speaking of the temple of His body" (John 2:21), and "when He had risen from the dead, His disciples remembered that He had said this to them" (John 2:22). Peter adds that "His soul was not left in Hades, nor did His flesh see corruption" (Acts 2:31). His flesh was raised before it could decay.

The usual objection

Many people treat the resurrection as something other than a body raised from the grave. Some hold that Christ's death did all the saving, and His rising only showed that it had worked. Others hold that He rose only in spirit, or lives on in His followers, while His body stayed in the tomb. Either way, salvation would stand even if His body had never left the grave.

Paul says that if Christ is not risen, believers are still in their sins. The rising is not an extra added to a salvation already complete; without it, no one is forgiven. And the rising Scripture speaks of is of the body. Jesus told His frightened disciples He was not a spirit, showed them His hands and feet, and ate in front of them. A spirit living on while the body stayed in the tomb is not what Scripture calls His resurrection.
