Charles Spurgeon Commentary Isaiah 45:18-19

"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 45:18-19 (ASV)

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, Seek ye me in vain; I the LORD speak righteousness, I declare things that are right.

Here is the glory of our God—that his every word is true, and that he has never said, in any place, that which contradicts what he has spoken in public to his people. You may safely rest upon the God who is always the same, who never plays fast and loose with his promises, or speaks anything in secret contrary to his pledged word. He is as true as he is sovereign; therefore, rely on him.
