What does the Bible say about the hope of believers after death?

The Bible assures believers that death is not the end but a transition to eternal life in the presence of God. In 1 Thessalonians 4:13-18, the Apostle Paul emphasizes that we should not grieve like those who have no hope because believers who have died are with the Lord. Their 'sleep' is temporary, and at the return of Christ, they will be resurrected and reunited with their bodies, experiencing eternal joy and fellowship in Heaven. This hope is grounded in the resurrection of Jesus, which serves as a guarantee for believers that they too will be raised.
