2. Christ gives us distinct knowledge of whither we should go. It is not enough to give general directions; we need to know what our next step is to be. It is of no avail that we see the shining turrets far off on the hill, if all the valleys between are unknown and trackless. Well: we have Him to point us our course. He is the exemplar--the true ideal of human nature. Hour by hour His pattern fits to our lives. True, we shall often be in perplexity, but that perplexity will clear itself by patient thought, by holding our wills in suspense till He speaks, and by an honest wish to go right. There will no longer be doubt as to what is our law, though there may be as to the application of it. We are not to be guided by men's maxims, nor by the standards and patterns round us, but by Him. 3. Christ gives means by which we can reach the aim. He does so by supplying a stimulus to our activity, in the motive of His love; by the removal of the hindrances arising from sin, through His redeeming work; by the gifts of new life from His Spirit. 'The labour of the foolish wearieth every one of them, because he knoweth not how to go to the city.' But he that follows Jesus treads the right way to the city of habitation. 4. Christ goes with us. The obscure words, 'It shall be for those' are by some rendered, 'He shall be with them,' and we may take them so, as referring to the presence with His happy pilgrims of the Lord Himself. Perhaps Isaiah may have been casting back a thought to the desert march, where the pillar led the host. But at all events we have the same companion to 'talk with us by the way,' and make 'our hearts burn within us,' as had the two disconsolate pedestrians on the road to Emmaus. It is Jesus who goes before us, whether He leads us to green pastures and waters of quietness or through valleys of the shadow of death, and we can be smitten by no evil, since He is with us. III. The travellers upon God's highway. Two conditions are laid down in the text. One is negative-the unclean can find no footing there. It is 'the way of holiness,' not only because holiness is in some sense the goal to which it leads, but still more, because only holy feet can tread it, holy at least in the travellers' aspiration and inward consecration, though still needing to be washed daily. One is positive--it is 'the simple' who shall not err therein. They who distrust themselves and their own skill to find or force a path through life's jungle, and trust themselves to higher guidance, are they whose feet will be kept in the way. No lion or ravenous beast can spring or creep up thereon. Simple keeping on Christ's highway elevates us above temptations and evils of all sorts, whether nightly prowlers or daylight foes.
