Final answer:
The question concerns the central Christian belief in the resurrection of Jesus Christ. Without Christ's resurrection, Christian faith would lose its foundation because the resurrection is integral to the belief in Jesus as the savior.
Step-by-step explanation:
The question "If Christ be not risen, then what becomes of our faith?" relates directly to Christian beliefs surrounding the resurrection of Jesus Christ, as described in the New Testament. The resurrection is a cornerstone of Christian faith, signifying Jesus's victory over death and his role as the messiah. Should Christ not have risen, Christian doctrine suggests that the foundations of their faith would be invalidated, as the resurrection is crucial to the belief in Jesus as the savior and to the hope of eternal life for believers. The Incredulity of Thomas and accounts of the empty tomb underline the importance of the resurrection in Christian theology and the subsequent spread of Christianity by the disciples.
