In Christianity, one of the beliefs is that the original sin separates humans from God. The concept of original sin refers to the sinful nature inherited by every human being as a result of the disobedience of Adam and Eve in the Garden of Eden.

This is often accomplished through the sacraments, especially baptism and confession.
