How do we know Jesus truly died on the cross?

The certainty of Jesus' death on the cross is substantiated by several factors presented in the Gospels. Mark 15 recounts that a centurion, an official tasked with ensuring executions were carried out, affirmed that Jesus was dead before he released the body to Joseph of Arimathea. Additionally, the practice of breakage of the legs to expedite death further emphasizes Jesus' death, as noted in John 19:31-33, where no bones were broken because He was already dead. This evidence refutes theories suggesting Jesus merely swooned or was unconscious, ensuring that believers can be confident in His sacrificial death.
