Sufficient unto the day is the evil thereof

Sufficient unto the day is the evil thereof.

Prov. You should not worry about things that might happen in the future.; It is enough to worry about things that are happening today. (Biblical.) Jane: I can't get to sleep; I keep thinking about the interview I have to do tomorrow. Alan: If the interview is tomorrow, worry about it tomorrow. Sufficient unto the day is the evil thereof.

When I am frantic about how I am going to get through my week, I sing the Apostle Matthew's "Consider the Lilies of the Field," as I once did in Spelman's chapel, and am reminded that "sufficient unto the day is the evil thereof." It helps me do what is at hand rather than worry about what has to be done tomorrow and next week, and prompts me to remember that God knows and will meet our needs if we will but trust Him.
