1 Thessalonians 4:13–18’s teaching on the resurrection and the state of believers after death aligns with the Westminster Confession of Faith, Chapter 32, which teaches that the bodies of believers, being still united to Christ, rest in their graves until the resurrection, while their souls are made perfect in holiness and received into the highest heavens to behold the face of God. The sermon’s emphasis on grieving with hope and the future bodily resurrection reflects this biblical doctrine of the intermediate state and final resurrection glory.
