"in Christ shall all be made alive." (1 Corinthians 15:22)
This says it better than I could:
His Resurrection was the greatest event in human history... Through His redeeming sacrifice all men shall rise from the grave. He has opened the way whereby we may gain not only immortality but also eternal life. Of all the things for which I feel grateful, I am most thankful for the gift of my Lord and my Redeemer.
