"Thus God, determining to show more abundantly to the heirs of promise the immutability of His counsel, confirmed it by an oath, that by two immutable things, in which it is impossible for God to lie, we might have strong consolation, who have fled for refuge to lay hold of the hope set before us." (Heb. 6:17-18)

"If any man living has found one promise untrustworthy, let him publish it to the world; and the heavens will clothe themselves in sackcloth, and the sun and moon and stars will reel from their seats, the universe will rock, and a hollow wind moan through creation, bearing the tidings that God is mutable, that God can lie. And that voice will be the herald of universal dissolution. But it can never, never be. Heirs of promise! God's power is eternal, His counsel is immutable. Heaven and earth may pass away, but His word shall never pass away. Ye therefore may have strong consolation; though ye lose all else, our heritage in the word and oath of God shall be unimpaired, world without end."
