Christianity is based upon the principle that everyone is a sinner. This doesn't mean that God has ridiculously high standards or that once you thought about stealing your cousin Beth's cupcake at a family picnic. It means that God sees through to the heart of you and understands and knows all the evil and petty and vindictive thoughts and deeds in your life. When you've lied to others to get your way, cheated, manipulated, bullied, insulted, stolen, and done all the horrible things that every single person does in their life, it stains you with Sin. Hell is a concept introduced during the corruption of the religion as it moves into pagan Greece, and is essentially an overly literal perversion of the fundamental concept of sin. Sin doesn't send you to Hell. Living in Sin is Hell. All the wicked thoughts and deeds that people justify in fucking one another over in everday life and in disobeying the laws of God poison their lives and fill them with misery. Only through repentance and forgiveness, constant repentance and forgiveness, as humans constantly fall back into Sin, can you cleanse your soul and acchieve a peace with God.


Also, most of the actual "sins" of the church are greatly exaggerated or flat-out lies.
