"Death, be not proud"

"Death, be not proud, though some have called thee
Mighty and dreadful, for thou art not so;"

I an not sure if I understood this poem correctly.  I understood that the speaker was addressing death through apostrophe.  The speaker was telling death not to be proud.  The speaker gives different reasons why death should not be proud.  The above quote is an example of the speaker's reasons.  I think the speaker is a man of assured faith with a firm conviction that death is not to be feared.  In the end of the poem, it says "we wake eternally, / And death shall be no more."  This is a reference to the Christian belief that we will all rise from the dead and live in eternity with God and defeat death.
