The great doctrine of the unity of the Church upon earth is, it is to be feared, feebly apprehended and feebly carried out, even by the most spiritually minded and intelligent of the Lord's people. The reason of this is very apparent. The doctrine is viewed rather in the light of the Church's present condition, than of her condition as presented in the New Testament; and this being so, the unity never can be understood. If we simply take Scripture for our guide, we shall have no difficulty about it. There we read, "If _one_ member suffer, _all_ the members suffer with it." This principle did not hold good in the days of king Jehoshaphat, because the body of Christ, properly so called, had no actual existence. All the members of it were written in God's book; but "as yet there was none of them"--they existed in the purpose of God, but that purpose had not been actualized. Hence, though so many were led astray by the influence of Jehoshaphat, it was not by any means on the principle stated in the above passage; it was not all suffering from the act of one because they were one body, but many being led astray by one because they followed his example. The distinction is very important. There is no member of the Church, how obscure soever, whose path and conduct do not affect, in some measure, all the members. "By one Spirit are we all baptized into one body, whether we be Jews or Gentiles, whether we be bond or free; and have been all made to drink into one Spirit." Hence, if a Christian be walking loosely or carelessly,--if he be out of communion,--if he fail in prayer, in watchfulness, or in self-judgment, he is really injuring the whole body; and, on the contrary, when he is walking in spiritual health and vigor, he is promoting the blessing and interest of all. It was not without a struggle that Jehoshaphat yielded to the solicitations of Ahab. The working of conscience is observable in the words, "Inquire, I pray thee, at the word of the Lord to-day." But ah! how futile was prayer for guidance, when he had already said, "I am as thou art, and my people as thy people; and we will be with thee in the war"! It is but solemn mockery to ask for guidance when we have made up our minds; and yet how frequently we do so! How frequently do we decide on a course of action, and then go and ask the Lord about it! All this is wretched; it is only honoring God with the lips, while the heart is in positive rebellion against Him. Instead of getting that guidance for which we profess to ask, may we not rather expect a lying spirit to be sent forth to us? (_v_. 21.) Ahab was at no loss for counselors. He speedily "gathered together four hundred prophets," who were ready to counsel him according to his heart's desire: "Go up, for God will deliver it into the king's hand." This was what he wanted. Nor need we marvel at Ahab's being quite satisfied with prophets like these. They suited him well.
