One secret of a sweet and happy Christian life is learning to live by the day. It is the long stretches that tire us. We cannot carry the load until we are three score and ten. We cannot fight the battle continually for half a century. But really there are no long stretches. Life does not come to us all at one time; it comes only a day at a time. Even tomorrow is never ours until it becomes today, and we have nothing whatever to do with it but to pass down to it a fair and good inheritance in today's work well done.
