By the resurrection of the Antichrist, Satan imitates the resurrection of Jesus Christ and makes the world wonder after the Beast.        

This adds to his importance and power.

               If this happens in the middle of the week, [middle of the Great Tribulation] at the time the Dragon is cast out of heaven, it will explain the change taken place in the Antichrist before receiving the deadly wound.

                        He was kind and giving before but after he recovers he becomes devilish as a result of Satan possessing him.
