“Thus Saith the LORD” is a very powerful expression. It has authority because it quotes God. We know that God does not lie. Everything He says is authentic and reliable. Unfortunately, we see people giving messages supposedly from God but what they say is against the written Word of God. God does not contradict Himself “For God is not the author of confusion, but of peace, as in all churches of the saints.” (1Cor. 14:33). There are many lying spirits in the world therefore we must test every spirit if they are of God. No private prophecy, vision, dream or revelation is above the Scriptures. The Holy Bible is our final authority. Whatsoever revelation that does not agree with the Bible should be discarded.
