"Death, be not proud" by John Donne - Oh this guy

"And death shall be no more; death, thou shalt die." I'm catching on to this John Donne guy! He is a Christian poet whose themes constantly revolve around the victory of God over evil. This poem alludes to the Resurrection. Through Jesus' death and with God, we can overcome death. One of the questions asked if the speaker was strong in faith, or if he was trying to convince himself that there is nothing to fear in death. I believe that this man is strong in faith. I see him as proclaiming his faith to others, to help them be free from fear. This man is proclaiming the victory of God over death, for mankind may now live in eternity. But he also has a tone of gloating - one that will not win one eternal life. The last two lines seem like neener-neener lines. He seems too proud of his proposed victory over death. In a sense, I can see him questioning himself. All of us have doubt at some point or other, this very well may be his attempt at burying that doubt.
