What is what does atonement mean?

Atonement is the act of making amends or reparation for a wrongdoing, either through an apology or through some form of compensation or restitution. It is a term often used in religious contexts, particularly in Christianity, where it refers to the process by which a person's sins are forgiven or absolved through the sacrifice of Jesus Christ on the cross. In general, atonement is about restoring balance or harmony after a breach has occurred, and it is seen as a necessary step towards healing and reconciliation.
