Final answer:
John Donne's poem 'Death be not proud' suggests that eternal life will ultimately triumph over death, as death itself is depicted as a temporary state that will be vanquished.
Step-by-step explanation:
According to the speaker in John Donne's poem 'Death be not proud', eternal life will finally triumph over death. This triumph is celebrated in the concluding lines of the poem, where Donne expresses that death itself will die. The poet challenges the conventional perception of death as mighty and dreadful, instead presenting it as a temporary state that will be overcome by the souls' resurrection and eternal life, as promised by Christian faith.
Donne, through his use of apostrophe, addresses Death as if it were a person, undermining its power and presenting the idea that humans have a more enduring existence beyond physical death. The ultimate victory is not that of death, but of immortal life, which will prevail when death is rendered powerless and no longer feared.
