The thing that thou doest is not good, etc. Exodus 18:17, 18. In the error of Moses, and the amendment suggested by Jethro, are to be discovered most valuable lessons. This day in the life of Moses was a microcosm of all his days. His whole life was service. So with all true life. But in such a life mistakes are possible. We inquire then what are the Divine conditions of a life of true ministry?

I. CHARACTER. The elements were laid down by Jethro as qualifications of the new judges. Certain that Moses possessed them. So must all who aim at usefulness (ver. 21).

1. Ability. Strange that ability comes first; but so it must be. Piety without ability can adorn only obscurity. Service and responsibility demand the man of power. Ability may be natural; but is also to be acquired. Hence duty of hard work, especially in morning of life.

2. Piety. Ability is the engine of the soul, the fear of God the helm. Richard Cobden was wont to say: - "You have no security for a man who has no religious principle." Said his colonel to Hedley Vicars, offering him in 1852 the adjutancy of his regiment: - "Vicars, you are the man I can best trust with responsibility."

3. Truth.

4. Disinterestedness.

II. ECONOMY, i.e., of force and of resource (vers. 17, 18). Remark: -

1. That the most earnest are likely to neglect it. It is not the hack but the thoroughbred that needs to be held in. The energy of Moses led him into error. So earnestness kills itself with excess of work.

2. That there is necessity for economy. As with money, one must not spend 25s. a week, if one has only 20s.; so there is a limitation as to strength (of every kind), time, and opportunity.

3. That the economy is easy. The Christian worker should not attempt that which is above, beside, or beneath his power or vocation. Nor all that is on the level of his ability.

4. That the consequences will be abundant and rich. The result of division of labour in a factory; so with spiritual enterprise, the effects will be the enrichment of the Church, and the largest service for the world.

III. CONCENTRATION. The more we withdraw effort from that which is not within our own province, the more must we accumulate and concentrate energy upon that which is. - R.
