Im going to keep the message out of this...mostly
Without considering the pretty obvious push to believe in God (I do believe in God, but I think that talking about burning in hell is not a way to convert people or a positive message in general, which shouldnt all messages of God be positive? Look to Jesus and you should know that he only wants peace and would never threaten hell upon someone, only offer eternal salvation)
Anyways, the animation is great! You need to brush up on your anatomy, though, as many of the angles seemed very flat and that takes away quite a bit from the overal experience you are trying to go for. The voicing is good, but the very beginning he kind of sounds like he has a lisp. Next time dont be afraid to re-record bits to fix issues like that.
You have some great music going, and you kept a very consistent mood about everything. The radical mood-change at the end, which I think was very well executed, helped cast a more compassionate side to the character and definitely created a multi-faceted personality to the speaker.
10/10 ONLY for the animation itself, I dont judge based on message. (And neither should anyone else! Opinions are opinions and its not like we dont see controversial things on Newgrounds!)
