When David, therefore, confessed, that he was "a stranger and a sojourner with GOD, as all his fathers were," what was this, but an express declaration, that, though he was encircled with a diadem, and clad in the robes of royalty; though he had his residence in the metropolis of Judea, and exercised an absolute sovereignty over the whole realm; he considered himself, nevertheless, as a stranger in a strange land, far distant from his native country, surrounded by a multitude of enemies, who were perpetually upon the watch to take advantage of any little mistake he might commit, perpetually in arms against him, and determined, if they possibly could, to rob him at once of his kingdom and his peace? What was it, but an humble acknowledgment of his own spiritually helpless and indigent condition? and at the same time an affectionate intimation of his secret hope, that, as his forefathers had been in the same circumstances he was now in, and had experienced the kind interposition of Heaven for their relief and comfort, GOD would be graciously pleased to continue to him the same loving-kindness, accompany support and protect him through his painful sojourn, and conduct him safe to those blessed abodes, which he had prepared for the reception of every true spiritual Israelite? "For I am a stranger with thee, and a sojourner, as all my fathers were." Upon this view of things, and under the influence of these principles, he composed the pathetic psalm, from whence my text is taken; which exhibits to us a lively representation of the vanity and shortness of human life, the difficulties that attend our pilgrimage through this world, the prudence and circumspection which the pilgrim must observe, the enemies he must expect to encounter on the way, and the confidence he must repose in the strength of a superior and Almighty arm, in order to secure to himself Success and Victory. The truth of this representation we find abundantly confirmed by the whole tenor of Scripture. The grand apostate seraph is there called "the prince of this world, the prince of the power of the air;" from which, and other expressions of the like import, we may justly conclude, that he was once in possession of this very system which we inhabit--it was the sphere of glory, in which he moved, whilst his lustre yet remained unfaded. Envious, jealous of its new inhabitants, he is perpetually "walking about, seeking whom he may devour." He avails himself of that earthly nature which we inherit from our fallen ancestor, insinuates himself through its foul channels into our inmost hearts, seduces us from the paths of innocence and virtue, and, unless timely rescued by a Superior Power, will hurry us headlong into the depths of his own dark and fiery kingdom.
