"For many walk, of whom I have told you often, and now tell you even weeping, that they are the enemies of the cross of Christ: whose end is destruction, whose god is their belly, and whose glory is in their shame - who set their mind on earthly things. For our citizenship is in heaven, from which we also eagerly wait for the Savior, the Lord Jesus Christ, who will transform our lowly body that it may be conformed to His glorious body, according to the working by which He is able even to subdue all things to Himself." Php 3:18-21
When Jesus returns to earth, He will physically raise all the dead, giving them back the bodies they lost at death. These will be the same bodies people had in earthly life—but our resurrected bodies shall never die and, for the elect, shall be place in a glorified state - no more suffering, pain, thirst or hunger. They will be able to do the many amazing things Jesus could do with His glorified body such as walk through walls and disappear.
We must pray, pray and never cease to pray that we may, by God's great mercy, be counted among His elect. May we not be resurrected to eternal suffering and damnation. All souls will be reunited with the body they had on earth - to be taken into Heaven or Hell. Pray for the conversion of sinners and the salvation of souls. The thought of even one person lost forever is an unspeakable tragedy which can never be undone!
