“Thus saith the Lord, Ye shall not go up, nor fight against your brethren the children of Israel: return every man to his house; for this thing is from Me.”- 1 Kings 12:24

What power was possessed by God’s prophets under the Old Testament. Here is one Shemaiah,-some of you never heard of him before, perhaps you will never hear of him again; he appears once in this history, and then he vanishes; he comes, and he goes,-only fancy this one man constraining to peace a hundred and eighty thousand chosen men, warriors ready to fight against the house of Israel, by giving to them in very plain, unpolished words, the simple command of God: “Thus saith the Lord, Ye shall not go up, nor fight against your brethren, the children of Israel: return every man to his house;” and it is added, “they hearkened therefore to the Word of the Lord, and returned to depart, according to the Word of the Lord.” Why have we not such power? Peradventure, brethren, we do not always speak in the name of the Lord or speak God’s Word as God’s Word. If we are simply tellers out of our own thoughts, why should men mind us? If we speak the word which we ourselves have fashioned, what is there in our anvil that it should command respect for what we make upon it? But if we can rise to the height of this great argument, and speak the truth as messengers of God, and there leave it, believing in it ourselves, and expecting great results from it, I wot that there will come more from our ministries than we have ever seen as yet. When the apostle Peter spoke to the lame man at the temple gate, he said, “In the name of Jesus Christ of Nazareth rise up and walk;” and he did rise up and walk because the name of Jesus Christ was relied upon; and we have need to preach the gospel, not as though our suasion, much less our oratory, were to prevail with men, but believing that there is an intrinsic power in the gospel, and that God the Holy Ghost will go with it to work the divine purpose, and accomplish the decrees of the Most High. We have need to stand near to God, and to be more completely overshadowed by His presence, and to be ourselves more fully believers in the Divine Majesty, and then shall we see greater things than these. ~ C.H.
