Yesterday is history, tomorrow is a mystery, today is a gift from God, which is why we call it the present. (Bill Keane, late American cartoonist)
It’s a play on words, of course: the present day is a gift from God. So was yesterday as tomorrow will be, too. If we spend too much time fretting about the failures of the past or worrying about tomorrow, we miss out on what’s happening today. Counting too much on the future spoils today, too. So, carpe diem, value today and fill it with purposeful effort.
Do not worry about tomorrow, for tomorrow will worry about itself. Each day has enough trouble of its own (Matthew 6:34).
