Boast not yourself of tomorrow; for you know not what a day may bring forth.
All Commentaries on Proverbs 27:1 Go To Proverbs 27
Caesarius of Arles
“You know not what any day may bring forth.” “Between morning and evening the weather changes.” Elsewhere we are also advised with a salutary precept: “Let us walk while we still have the light, before darkness comes over us.” Now some careless person may say, When I reach old age, then I shall have recourse to the healing of repentance. The wretched person does not know that if one has been accustomed to commit sins with a promise of repentance, never or only with difficulty will he merit to obtain the fruit of repentance.
