"A little pause prepares the mind for greater service in the good cause.. .Fishermen must mend their nets. And we must every now and then repair our mental waste and set our machinery in order for future service. To tug the oar from day to day, like a galley slave who knows no holidays, suits no mortal men. Mill streams go on and on forever, but we must have our pauses and our intervals.
Who can help being out of breath when the race is continued without intermission? Even beasts of burden must be turned out to grass occasionally. The very sea pauses at ebb and flood. Earth keeps the sabbath of the wintry months. And man, even when exalted to be God's ambassador, must rest or faint; must trim his lamp or let it burn low; must recruit his vigor or grow prematurely old. It is wisdom to take occasional furlough.
In the long run, we shall do more by sometimes doing less. On, on, on forever, without recreation, may suit spirits emancipated from this 'heavy clay'; but while we are in this tabernacle, we must every now and then cry halt and serve the Lord by holy inaction and consecrated leisure.
Let no tender conscience doubt the lawfulness of going out of harness for awhile, but learn from the experience of others the necessity and duty of taking timely rest."
- Charles Spurgeon
