From a church bulletin:

The Resurrection of Jesus… was the ultimate human experience. For the first time, a human brain and a human nervous system were suffused from within by the energies of the Resurrection. The whole, material universe begins to be transformed from that moment to what Paul will call “the fullness of Christ.” For the first time, a human heart pulsed with a life beyond the power of death, the pulsation of a heart which will never stop. For all eternity that heart will beat.

Jesus was thereby manifest as the “firstborn from the dead” as he is called in the book of Revelation. His experience of rising from the dead, the first man to do so, is the secure promise of the glory that awaits all those who are joined to him in faith and Divine Grace. This will be the final stage of Salvation. The final stage of Salvation will come only at the end of the world. You see, even dying and going to heaven is not the last stage. It’s a rather important one, but it’s not the last stage. True Soteria—True Salvation—is found when our bodies will rise in glory.
