Quote from Judica - Luther's Complete Sermon for the Fifth Sunday in Lent
A Christian has that Word and clings firmly to it in death; therefore he does not see death, but his eyes are filled with the life and the Christ in that Word; therefore he never feels death. But the godless possess not that Word, therefore they see no life, but only death; and they must also feel death; that is then the bitter and eternal death.
11. Now Christ means here that whoever clings to his Word will in the midst of death neither feel nor see death, as he also says in John 11:25: “I am the resurrection, and the life: he that believeth in me though he die, yet shall he live,” that is, he will not experience real death. Here we see now what a glorious estate it is to be a Christian, who is already released from death forever and can never die. For his death or dying seems outwardly indeed like the dying of the godless, but inwardly there is a difference as great as between heaven and earth. For the Christian sleeps in death and in that way enters into life, but the godless departs from life and experiences death forever; thus we may see how some tremble, doubt and despair, and become senseless and raging in the midst of the perils of death. Hence death is also called in the Scriptures a sleep. For just as he who falls asleep does not know how it happens, and he greets the morning when he awakes; so shall we suddenly arise on the last day, and never know how we entered and passed through death.
