The text may be said to comprise every other prayer. If God gives His servant to "know the way wherein he should walk," and strength to walk in it, peace, and order, and liberty, and joy will soon come. Life is a daily difficulty. Think of the number of things that are to be believed, that are to be renounced, that are to be examined, that are to be distinguished in themselves and from other things, that are to be tentatively dealt with, that are to be done, that are to be left undone, that are to be waited for, that are to be suffered. All these are included in the "way wherein we should walk."
I. Opinions and beliefs. There can be no living way for a man that does not involve these. We are bound to form them, and the point is that there is very great difficulty in forming some of them or in keeping them when we have them. Any one of us, if we will, may be of them that believe to the saving of the soul. How? By bringing the whole case fully and earnestly before God. If we come really to Him, we have solved the difficulty, we have come into the new and living way, and God will make that way more and more plain before our face; whereas if we abide among the exterior things examining, considering, comparing, putting this opinion against that, and working the whole matter simply as a high intellectual problem, without ever making the last and highest appeal we have no certainty of a good and true issue.
II. Conduct. In respect of conduct also we find life to be a scene of constant difficulty. Even those who know the way they should go, so far as it consists of beliefs, convictions, principles, find it still in their practice to be a way of continual difficulty. What can we do? We can pray. We can use this text and get the benefits it carries. The solution of all difficulty, be it what it may, is "to lift up the soul to God." God is the God of peace; and to lift up the soul to Him is to rise out of storm into calm, is to leave the self-made troubles of life beneath us while we mount up on eagles' wings into His eternal and illimitable tranquillity.
