Luke 16:10

He that is faithful in that which is least, etc. - He who has the genuine principles of fidelity in him will make a point of conscience of carefully attending to even the smallest things; and it is by habituating himself to act uprightly in little things that he acquires the gracious habit of acting with propriety fidelity, honor, and conscience, in matters of the greatest concern. On the contrary, he who does not act uprightly in small matters will seldom feel himself bound to pay much attention to the dictates of honor and conscience, in cases of high importance. Can we reasonably expect that a man who is continually falling by little things has power to resist temptations to great evils?

He that is faithful ... - This is a maxim which will almost universally hold true. A man that shows fidelity in small matters will also in large; and he that will cheat and defraud in little things will also in those involving more trust and responsibility. Fidelity is required in small matters as well as in those of more importance.

16:10 And whether ye have more or less, see that ye be faithful as well as wise stewards. He that is faithful in what is meanest of all, worldly substance, is also faithful in things of a higher nature; and he that uses these lowest gifts unfaithfully, is likewise unfaithful in spiritual things.
