In 1 Thess 4:13 – 5:11, Paul responds to the Thessalonians' inquiry about the Lord's coming. Paul reveals a distinct contrast between those who believe and those who do not. For those who belong to Christ, Paul declares that they possess salvation through Christ. He identifies salvation as involving faith in the death and resurrection of Christ. In this faith, God brings those alive and dead to him in Christ. This gathering occurs by his calling of first those who died and then those who have "the sleep of death". Together those who gather will join God in heaven.
