Matthew 28

The presence of a sealed tomb and Roman guards did not stop Jesus from fulfilling His promise of resurrection!  Exactly three days after His death, the tomb was empty; not as the result of a robbery or a plot to fool the masses, but as the result of Jesus' bodily resurrection.  He was seen by many in the days following His resurrection.  The guards were told to concoct a story of robbery that would be covered by those in authority should the governor hear of it.  Meanwhile, Jesus told His followers to make disciples of others - telling them of who He is and what He has done.
