Two obvious characteristics of this guiding Light must be kept in view.
1. God's people were not led by a road already made and used, and which they could have studied from beginning to end on a map before starting; but they were led day by day, and step by step, by a living guide, who chose a route never before trodden. In the morning they did not know whether they were to go forward or back, or to stay where they were. They had to wait in ignorance till their guiding pillar moved, and follow in ignorance till it halted. Our passage through life is similar. It is not a chart we are promised but a guide. We cannot tell where next year or next month may be spent. We are not informed of any part of our future, and have no means of ascertaining the emergencies which may try us, the new ingredients which may suddenly be thrown into our life, and reveal in us what till now has lain hidden and dormant. We cannot tell by what kind of path we shall be led onwards to our end; and our security from day to day consists not at all in this, that we can penetrate the future, and see no dangers in it, but our security is that we shall always be guided by infallible and loving wisdom. We have learned a chief article of human wisdom if we have learned to leave to-morrow to God and faithfully follow Him to-day. A road as it lies in the distance often looks impassably steep, but as we approach and walk it step by step, we find it almost level and fairly easy.
2. This light was to guide, not their conduct, but their movements. All men need similar guidance. All men have practical matters to determine which often greatly perplex them; they must make a choice between one or other course of action that is possible. Steps which will determine their whole subsequent life must be taken or declined; and for the determining of such alterations in the place or mode of their life there is often felt great need of a guidance which can be entirely relied upon. Sometimes, indeed, our course is determined for us, and we are not consulted in the matter; as the pillar of fire was silent, assigning no reasons, condescending to no persuasion or argument, but simply moving forwards; passing over rugged and steep mountain ridges, past inviting and sheltered glens, offering no present explanation of the route, but justified always by the result. So we often find that our course is determined apart from our own choice, wishes, judgment, or prayers. But this we commonly resent, and crave a guidance which shall approve itself to our own judgment and yet be infallible; which shall leave us our freedom of choice, and yet carry us forwards to all possibilities of good. In fact, we would rather have our freedom of choice and the responsibility of guiding our own life, with all its risks, than be carried forward without choice of our own.
This is the great distinction between the light which Christ is and the light by which the Israelites were led from day to day. They had an external means of ascertaining promptly which way they should go. Their whole life was circumscribed, and its place and mode determined for them. The guidance offered to us by Christ is of an inward kind. A God without might seem perfect as a guide, but a God within is the real perfection. God does not now lead us by a sign which we could follow, though we had no real sympathy with Divine ways and no wisdom of our own; but He leads us by communicating to us His own perceptions of right and wrong, by inwardly enlightening us, and by making us ourselves of such a disposition that we naturally choose what is good.
