Jehoshaphat, however, failed to maintain this separation; and, as has been already remarked, in failing himself, led others into failure. In this we may learn a most solemn lesson. Jehoshaphat had, we may suppose, gained very considerable influence over the hearts of the people by his previous devotedness;--he had established himself in their confidence and affections; and, to a certain extent, rightly so. It is right that those who walk devotedly should be loved and confided in; but then we must watch most jealously against the dangerous tendency of mere personal influence. No one save a man of extensive influence could have said, "My people are as thy people." He might have said, "I am as thou art," but no more. His extensive influence, when used out of communion, only made him a more efficient instrument of evil. Satan knew this; he knew his mark; he did not fasten on an ordinary man of Judah, but on the most prominent and influential man he could find, well knowing that if he could only succeed in drawing him aside, others would follow in his train. Nor was he mistaken. Many would no doubt say, "What harm can there be in joining Ahab's expedition? Surely, if there were any thing wrong in it, such a good man as king Jehoshaphat would not engage in it. So long as we see _him_ there, _we_ may make our minds easy about the matter." But if this were not the language of some in Jehoshaphat's day, it certainly is of many in our own. How often do we hear Christians say, "How can such-and-such things be wrong, when we see such good men in connection with them, or engaging in them?" Now all that can be said of such reasoning is that it is utterly false; it is beginning quite at the wrong end. We are responsible to God to act upon principle, let others do as they may. We should be able, through grace, humbly, yet decidedly, to render a sound and intelligent reason for whatever course of action we may adopt, without any reference to the conduct of others. Moreover, we know full well that good men go astray, and do wrong things. They are not, therefore, nor can they be, our guides. "To his own master he standeth or falleth." A spiritual mind, a conscience enlightened by the Word of God, a real sense of personal responsibility, together with honesty of purpose, are what we specially need. If we lack these, our path will be defective. But it may be said, there are few, if any, who occupy a position in which their conduct could exert such an extensive influence as that of king Jehoshaphat. To meet this, it may be needful to dwell a little upon a truth sadly neglected in the present day, namely, that of _the unity of the body of Christ, and the consequent effect which the conduct of each member, however obscure, must produce upon the whole body_.
