It was good and sound advice that Jethro gave his son-in-law. It could hardly  have been better. It is always better to set one hundred men to work than  attempt to do the work of one hundred men. There is no greater art in the world  than to develop the latent capacities of those around us by yoking them to  useful service. But good though the advice obviously was, Jethro carefully  guarded Moses against adopting it, unless the Lord had been consulted, and had  commanded it.
Let us test human advice. - There are plenty of voices that  advise us, and each has some nostrum for our health, some direction for our  path. Some are true guides, whom God has sent to us, as Jethro to Moses. Often  an on-looker can see mistakes we are making, and can suggest something better.  But we are wise to get alone into the holy presence of God, and ask what He  commands, what is His will.
Let us test human teachings. - So full is the  world of voices, so bewildering the din of religious schools and sects! The  Apostle was justified in advising us to prove all things, and to try the  spirits, whether they were of God. There are four tests for truth: what  glorifies Christ; what humbles the flesh; what is in accord with the Word of  God; and what has stood the trial of Christian experience in the  past.
There is no teacher like God, and we may always detect His voice.  It is small and still; it casts down imagination, and brings our thoughts into  the captivity of Jesus; it is definite and distinct. When there is an indistinct  murmur of many sounds along the wire, you may be sure that you are not in  communication with your Father's person. When He speaks, there is no mistaking  His voice or His will.
