Zaccheus! make haste and come down; to-day I must abide in thy house.' Why must He? Because Zaccheus was to be saved, and was worth saving. What was the must'? To stop for an hour or two on His road to the Cross. So He teaches us that in a life penetrated by the thought of the divine will, which we gladly obey, there are no things too great, and none too trivial, to be brought under the dominion of that law, and to be regulated by that divine necessity. Obedience is obedience, whether in large things or in small. There is no scale of magnitude applicable to the distinction between God's will and that which is not God's will. Gravitation rules the motes that dance in the sunshine as well as the mass of Jupiter. A triangle with its apex in the sun, and its base beyond the solar system, has the same properties and comes under the same laws as one that a schoolboy scrawls upon his slate. God's truth is not too great to rule the smallest duties. The star in the East was a guide to the humble house at Bethlehem, and there are starry truths high in the heavens that avail for our guidance in the smallest acts of life.
So, brethren, bring your doings under that all-embracing law of duty--duty, which is the heathen expression for the will of God. There are great regions of life in which lower necessities have play. Circumstances, our past, bias and temper, relationship, friendship, civic duty, and the like--all these bring their necessities; but let us think of them all as being, what indeed they are, manifestations to us of the will of our Father. There are great tracts of life in which either of two courses maybe right, and we are left to the decision of choice rather than of duty; but high above all these, let us see towering that divine necessity. It is a daily struggle to bring I will' to coincide with' I ought'; and there is only one adequate and always powerful way of securing that coincidence, and that is to keep close to Jesus Christ and to drink in His spirit. Then, when duty and delight are conterminous, the rough places will be plain, and the crooked things straight, and every mountain shall be brought low, and every valley shall be exalted,' and life will be blessed, and service will be freedom. Joy and liberty and power and peace will fill our hearts when this is the law of our being: All that the Lord hath spoken, that must I do.'
