Reformed theology affirms the promise of eternal life and glorification for all those whom God has elected and who believe in Christ. At death, the souls of the elect are immediately with Christ (the intermediate state); at the Last Day, the dead are raised and the righteous enter into the fullness of eternal life. The Heidelberg Catechism (Q&A 57–58) grounds hope for resurrection directly in Christ's resurrection. The Westminster Confession (Chapter XXXII) specifies that believers' souls at death are made perfect in holiness and received into paradise.

Reformed eschatological hope is for the renewal of all creation — a new heaven and new earth — in which the glorified elect dwell in perfect fellowship with God forever. The goodness of the created order is affirmed and redeemed, not escaped. This is described in the Belgic Confession (Article 37) as the end toward which all history moves. Assurance of this future belongs to the doctrine of the perseverance of the saints: those whom God has elected will certainly be saved.
