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)
