All Christians who have died will one day rise from their graves and will meet the Lord in the air.  Christians who have not yet died will be raptured or caught up with them, to be with the Lord.  Then Christians of all ages will live with God forever.  The scriptural truth of the Lord’s soon return is “the Blessed Hope” (Romans 8:23; 1 Corinthians 15:51-52; 1 Thessalonians 4:16-17; Titus 2:13).
