1 Thessalonians 4:14

14 We believe that Jesus died and he rose again after death. So we also believe that people who have died as Christians will live again. When God brings Jesus back, he will also bring back with him the Christians who have died.

4:13The Christians at Thessalonica were confused about Christ's return. They were sad about their Christian friends who had died already. They did not know what would happen to those people.
