Paul advises us not to grieve as others do who have no hope concerning the dead in the Lord. In other words, we should not mourn for our loved ones who have died in Christ as if we have no hope of seeing them again. Rather, we should have faith that they are with the Lord and that we will be reunited with them in heaven. This gives us hope and comfort in the face of death, knowing that death is not the end and that we will be together again in the presence of God.
