In "Death, be not proud," how do paradox and personification signify a victory over death?no!

In my opinion, the author uses both paradox and personification to emphasize the idea that, in the end, it is life that will triumph over death.

The idea that death can die is a paradox.  By saying that this is possible, the author is making us think in a different way about our assumptions.  By making us think about this, he makes it easier for us to accept his premise.

By personifying death, the author helps with his paradox.  If death is human, then death must surely die.

So, the author is asking us to think about the idea that death can (through God) be "killed."  He uses personification and paradox to make us consider this possibility.
