This lesson makes life easy and simple!

(J.R. Miller, "Help for the Day")

"As your days — so shall your strength be!" Deuteronomy 33:25

Each day is, in a certain sense, a complete life by itself. It has . . .
  its own duties,
  its own trials,
  its own burdens,
  and its own needs.
It has enough to fill heart and hands for the one full day. The very best we can do for any day, for the perfecting of our life as a whole, is to live the one day well. We should put all our thought and energy and skill into the duties of each day, wasting no strength, either in grieving over yesterday's failures — or in anxiety about tomorrow's responsibilities.

We have nothing to do with life in the aggregate — that great bulk of duties, responsibilities, struggles, and trials which belong to a course of years. We really have nothing to do even with the nearest of the days before us — tomorrow.

Our sole business is with the one little day, now passing. Its burdens will not crush us — we can easily carry them until the sun goes down. We can always get along for one short day — it is the projection of life into the long future that dismays and appalls us. This lesson makes life easy and simple!

"Give us this day our daily bread." Matthew 6:11
