But, alas, through the corruption of our common nature, everything human is liable to be perverted. There are many who profess to be the Lord's messengers, who are not such. It is, accordingly, intimated in the Scripture, for the warning of Lord's people, that there are two classes of messengers, the evil and the good. In the history and prophecies of the Old Testament we read of false prophets who were not sent, and yet they ran and taught the people perverse doctrines and led many away from the true service of the living God. In the days of Israel in the wilderness there were Korah, Dathan and Abiram, who, contrary to the spirit of God, taught the people to rebel against Moses and Aaron. The Prophet Jeremiah speaks of a very busy set of false prophets who did not stand in the Lord's counsel and misled His people. And in the New Testament they are not missing,--there were the Pharisees, Judas, Hymenaeus, and Alexander. St. Paul bitterly complains about some who, to gain their own selfish purposes, pretended to be apostles, but who were not. Our Lord admonishes that, at all times of the Christian dispensation, we may expect false prophets wearing the clothing of sheep. Now, how are we to distinguish between the real and pretended messengers of Christ? The Lord Himself has told us: "By their fruits ye shall know them." If, therefore, a minister does not bring forth the proper fruits, say what he will to the contrary, he is not accredited by Christ,--he is not the Lord's messenger. One chief point by which we may judge is the "fruits of the lips." What message does he deliver? Is it the Lord's message, or is it some conceit of his own? The popish priest, who preaches salvation by works, the intercession of the Virgin, the lying delusion of purgatory, delivers not the Lord's message. The Unitarian minister, who talks of the virtues of humanity, who denies the Trinity, the atonement of the Redeemer, the converting and sanctifying operations of the Holy Spirit, he, too, certainly does not deliver the Lord's message. And to come nearer to ourselves, he who professes to be a Lutheran minister, and who yet denies the doctrine of Justification by Faith only, who does not preach the regenerating power of the Holy Sacrament of Baptism, and the real presence of Christ's body and blood in the Lord's Supper, he, likewise, whatever may be his profession to the contrary, does not deliver the Lord's message. What is the Lord's message? The voice said: "Cry," and the faithful messenger said: "What shall I cry?" "All flesh is grass. The grass withereth, the flower fadeth, but the Word of our God shall stand forever." "The prophet that hath a dream, let him tell a dream; and he that hath _my Word_, let him speak my Word faithfully."
