The practice of eschatology is to tell the truth about death, not to sugarcoat it. Death is horrible, and God is with us as we face that horror. Paul encourages Christians to claim the hope of the resurrection, not so that we will not grieve, but so that ours will not be the hopeless grief of those who do not know resurrection power (1 Thess. 4:13). The practice of Christian eschatology is to grieve and to hope, knowing that death will be followed by resurrection.
