“After the first morning hour the Christian’s day until evening belongs to work. “Man goeth forth unto his work and to his labour until evening” (Ps 104:23). In most cases the Christian family fellowship will separate for the duration of the working day. Praying and working are two different things. Prayer should not be hindered by work, but neither should work be hindered by prayer. Just as it was God’s will that man should work six days and rest and make holy day in His presence on the seventh, so it is also God’s will that every day should be marked for the Christian by both prayer and work. Prayer is entitled to its time. But the bulk of the day belongs to work. And only where each receives its due will it become clear that both belong inseparably together. Without the burden and labor of the day, prayer is not prayer, and without prayer work is not work. This only the Christian knows. Thus, it is precisely in the clear distinction between them that their oneness becomes manifest.”
