The literal translation from the Hebrew will be:
If there were no death, sin would never die. Through death alone is sin restrained, and there is no other way of getting rid of it. Such gracious and wholesome punishment God gives to us that sin is slain through death. Therefore we should receive death with joyful hearts and bear it as coming from a gracious Father, as the faithful do. For our Father’s goodness is so great that even death must serve to slay and to uproot all misfortune.
Therefore death is nothing but sheer grace, yes, even the beginning of life. For since it ministers to the restoration of the soul, our bodily system and all that is associated with it, such as illness, danger, pain, and labor, must also serve for our good, so that we could desire nothing better.
For Adam must die and decay before Christ can completely rise, and that begins with the life of repentance, and is perfected through death. Therefore death is a wholesome thing to all who believe in Christ, for all that is born of Adam death brings to decay and dust, that Christ alone may abide in us. (The Seven Penitential Psalms, 1517) (WA 1:188)
