Proverbs 6:10–11 (NKJV) — 10 A little sleep, a little slumber, A little folding of the hands to sleep— 11 So shall your poverty come on you like a prowler, And your need like an armed man.
A love of sleep results in poverty. Those who love sleep, those who are lazy, will fall into poverty. The implication is that poverty will overtake them as a person who travels quickly overtakes one who walks slowly, or like an armed robber.
These and other passages of Scripture teach us it is not wrong to save, but wise. Our level of spending should not automatically rise to meet the level of our income. Rather, we should set aside some of our income for future needs. Saving and paying cash for needed purchases is much wiser than borrowing, presuming on the future, and paying high interest rates.
