What did the christians believe about the after life and life on earth?

I'm not sure what they think about the life on earth, but they believe that when you die, you will enter the gates of Heaven and live an eternal life with peace and no worries. Or something along that line.

well, that's not entirely right. we believe that life on Earth is sacred from "the womb to the tomb." we believe that abortion is wrong, the death sentence is wrong (for the most part). we believe in pretty much anything that promotes life. as for the after life, we believe that God will judge us at the moment of our death. it will be like a slide show of our life in which he will judge our rights and wrongs and send us either to Heaven or Hell. Hell is eternal separation from God, while Heaven is eternal union with God. in heaven, we believe that there is no sin, therefore completely pure and peaceful, like the person above me said. life in either heaven or hell will be eternal. if god feels that you're still worthy of going to heaven but not completely ready, he will send you to a place called purgatory. purgatory is like a halfway mark where you will be purified until you are ready to go to heaven. every soul that goes to purgatory will eventually make it to heaven, none will go to hell. hopefully that summed it up for you!
