Always be prepared…

That God has promised you pardon when you amend your life, I cannot deny. But tell me, pray: I agree and I grant you and I know that God has promised you forgiveness. But who has promised you tomorrow? Where you read that you will receive forgiveness, when you do penance, read for me also how much longer you have to live. It is not there, you say. Therefore you do not know how long more you have to live. Then reform your life, and be always prepared.
–Saint Augustine (354-430)

However small the sins…

However small the sins that you may confess may be, always have sincere sorrow for them, together with a firm resolution to correct them in the future. Many who confess their venial sins out of custom and concern for order, but without thought of amendment, remain burdened with them for their whole lives and thus lose many spiritual benefits and advantages.
–Saint Francis de Sales (1567-1622)
