Charles Spurgeon Commentary Isaiah 45:16-19

"They shall be put to shame, yea, confounded, all of them; they shall go into confusion together that are makers of idols. [But] Israel shall be saved by Jehovah with an everlasting salvation: ye shall not be put to shame nor confounded world without end. For thus saith Jehovah that created the heavens, the God that formed the earth and made it, that established it and created it not a waste, that formed it to be inhabited: I am Jehovah; and there is none else. I have not spoken in secret, in a place of the land of darkness; I said not unto the seed of Jacob, Seek ye me in vain: I, Jehovah, speak righteousness, I declare things that are right." — Isaiah 45:16-19 (ASV)

They shall be ashamed, and also confounded, all of them: they shall go to confusion together that are makers of idols. But Israel shall be saved in the LORD with an everlasting salvation: ye shall not be ashamed nor confounded world without end. For thus saith the LORD that created the heavens, God himself that formed the earth and made it; he hath established, it, he created it not in vain, he formed it to be inhabited: I am the LORD; and there is none else. I have not spoken in secret, in a dark place of the earth: I said not unto the seed of Jacob, See ye me in vain: I the LORD speak righteousness, I declare things that are right.

It is a very comforting thing for us to be told, not only what God has said, but also what he has not said. Be sure of this, that there is nothing in the secret book of God's decrees, and nothing in the sealed book of prophecy, which is contrary to the gracious covenant promises God has revealed to his people in his Word. He does not say one thing, and mean another. You may rest assured that all the revelations that are yet to be given, if there are to be any (and some are always talking about fresh light breaking from the Word!), will never contradict what has been revealed of old.

God did not tell his ancient people anything which contradicts what he has told us. The poorest and humblest of his people, who have been able to spell out, in the Word of God, their right and title to the divine inheritance, may rely upon it that, if any wise man comes to them with some wonderful discovery which contradicts the Bible, he simply comes with a lie, for God has nowhere contradicted what he has plainly revealed in the Scriptures.
