Formation of Conscience
At the beginning of each day we should look ahead to what situations for serving God might arise and also what temptations we could face. Then we make a firm resolution to please God in both respects, by doing good and avoiding evil. De Sales recommends examining our conscience twice a day - at noon and at night. He also teaches us how to make a good confession, and what qualities to look for in a good confessor and spiritual director.
To keep it all working properly, he encourages all Christians to attend an annual retreat to take stock of progress made and to fix what might need fixing.
