I've never been in jail, murdered anyone, or even done drugs. Most would say I'm a "good" person, but I'm prideful, greedy and selfish. It's a conscious effort for me to be compassionate and caring towards others. The fact that there is even a way to be deemed perfect and blameless and worthy of heaven is where the compassionate, loving and merciful God comes in.
From a secular viewpoint, what separates Christianity from the other religions is the death, burial and resurrection of a Savior. There's nothing for it's followers to do to appease God.
