You can be assured the Roman guards performed their duty with total dedication and absolute efficiency because the penalty under Roman law for falling asleep or leaving their post unguarded was death! In fact, the last thing the Roman guards wanted was an incident like this to happen because it would put their lives in jeopardy. And think about this: Would anyone in their haste to steal the body take the time to first remove the linen and then neatly roll up the face cloth of Jesus? I think not!
And if the body truly remained in the tomb, and yet the disciples still made claim to the resurrection, then all the Romans or Jews needed to do was simply produce the body of Jesus and display it in the streets where all could see it. This would have immediately disproved and cancelled any false message the disciples may have claimed concerning the resurrection and thus, the movement of Christianity would have instantly been terminated.
Fortunately, it is easy to see that there really is only one possible and logical answer: Jesus Christ was resurrected and truly is the son of God!
The sheer conviction of His disciples also gives us additional proof that Jesus was indeed resurrected! After Jesus was crucified but before the resurrection took place, the disciples became one what unsure of their beliefs and actually turned into incredibly timid men who literally feared for their lives! The disciple Peter was so scared during the trial of Jesus, he actually denied three times even knowing who Jesus was (Luke 22:61). Even though they witnessed the phenomenal teachings and miracles of Jesus, the Bible tells us that on resurrection night, the assembled disciples were gathered behind locked doors for fear of the Jews (John 20:19). But something happened in the lives of these disciples that instantly changed them! They went from being intimidated men who were unsure of their beliefs, into bold lions that were unshaken in their faith! What event was capable of making such profound change in their timed lives? The answer is simple: They were eyewitnesses to the resurrection of Jesus Christ!
These twelve disciples who were once weak and unsure had now become so courageously bold that eleven of them were put to death by the cruelest methods known because of their message of the resurrection and their belief in Jesus as the Son of God. Only John died a natural death. All the others were killed by either crucifixion; the sword; the spear; arrows; and even stoned to death!
