when you say that it belittles what Jesus did on the cross, i think that you are really just being selfish. you think that because you've lived this "holy" life, that because really you like to think that you're somehow better than these people who aren't "saved," that you deserve this wonderful afterlife. but  what makes you so special? because you half-heartedly, mumbled a pitiful prayer, and siad to your god, "i'm wrong, and i really want to change." that you deserve to go to heaven? well the fact is you hated, you lied, you sinned just like the rest of us.
really what belittles what Jesus did, is you telling people that there is a hell. and that Jesus' blood doesn't cover all. it only covers the elite. you are selfish. and it's not okay
