The taking up of the ark by the priests was a decisive step. There could be no resiling now from the course entered on. The priests with the ark must advance, and it will be seen whether Joshua has been uttering words without foundation, or whether he has been speaking in the name of God. Shall mere natural forces be brought into play, or shall the supernatural might of heaven come to the conflict, and show that God is faithful to His promise? Let us put ourselves in Joshua's position. We do not know in what manner the communications were carried on between him and Jehovah of which we have the record under the words "the Lord spake unto Joshua." Was it by an audible voice? Or was it by impressions on Joshua's mind of a kind that could not have originated with himself, but that were plainly the result of Divine influence? In any case, they were such as to convey to Joshua a very clear knowledge of the Divine will. Yet even in the best of men nature is not so thoroughly subdued in such circumstances but that the shadow of anxiety and fear is liable to flit across them. They crave something like a personal pledge that all will go well. Hence the seasonableness of the assurance now given to Joshua--"This day will I begin to magnify thee in the sight of all Israel, that they may know that, as I was with Moses, so I will be with thee." How full and manifold the assurance! First, I will magnify thee. I will endue thee with supernatural might, and that will give you authority and weight, corresponding to the position in which you stand. Further, this shall be but the beginning of a process which will be renewed as often as there is occasion for it. "This day I will _begin_." You are not to go a warfare on your own charges, but "as your days, so shall your strength be." Moreover, this exaltation of your person and office will take place "in the sight of all Israel," so that no man of them shall ever be justified in refusing you allegiance and obedience. And to sum up--you shall be just as Moses was; the resources of My might will be as available for you as they were for him. After this, what misgivings could Joshua have? Could he doubt the generosity, the kindness, the considerateness of his Master? Here was a promise for life; and no doubt the more he put it to the test in after years the more trustworthy did he find it, and the more convincing was the proof it supplied of the mindfulness of God.
