The term 'require forgiveness' can be summarized by the three letter word 'SIN'. SIN is a religious concept that refers to an action or omission that violates a moral rule. It is often seen as an offense against God or a transgression of divine law. In Christianity, SIN is seen as a form of disobedience to God and is believed to have consequences both in this life and the afterlife. Forgiveness is the act of pardoning someone for their wrongdoings and is seen as a necessary part of repentance and reconciliation with God.
