Death?

“Death in the true sense is separation from God, and “the sting of death is sin” (1 Cor 15:56). Adam, who received the sting, became at the same time an exile from the tree of life, from paradise and from God (Gen 3); and this was necessarily followed by the body’s death. Life, in the true sense, is He who said, “I am the life” (John 11:25), and Who, having entered into death, led back to life him who had died.” – St Maximus the Confessor, 400 Chapters on Love
