Before celebrating the Sacrament of Penance, ask God for help to examine your conscience. Spend time reviewing your conduct in light of the commandments and the example of Christ. Be prepared to tell the priest the specific sins you have committed, and to the best of your ability, how many times you have committed them since your last confession. Avoid generalizations and inform the priest of any relevant circumstances in which your sins were committed.
Below are examples of different prayerful examinations of conscience that you can use as you prepare for your confession.
