Death, Be Not Proud: Central Purpose

I think that the speaker's central purpose in this poem was to convey that people shouldn't fear death. He describes death as not being "mighty and dreadful" as some have called it. Conversely, he goes as far to ask death to kill him. The speaker describes death as just a simple step until "we wake eternally" where death does not exist. The poem takes an unorthodox approach to look at death in a positive light. The speaker, obviously a man of faith, describes death as the last thing between people and their eternal life after. One of the things I didn't understand from this poem though is why he is telling death to not be proud. The speaker describes all the good things of death and then says for it to not be proud. Usually when we think of good things or qualities, there is a sense of pride that comes along with it. Paradoxically, the author conveys that this is not the case which has left me a little confused on the theme or if my understanding of this poem is right.
