"My soul, it is God, even thy God, God that cannot lie, who speaks to thee. This word of His which thou art now considering is as true as His own existence. He is a God unchangeable. He has not altered the thing which has gone out of His mouth, nor called back one single consolatory sentence. Nor doth He lack any power; it is the God that made the heavens and the earth who has spoken thus. Nor can He fail in wisdom as to the time when He will bestow the favours, for He knoweth when it is best to give and when better to withhold.
"Therefore, seeing that it is the word of a God so true, so immutable, so powerful, so wise, I will and must believe the promise."
—Charles Haddon Spurgeon, Morning and Evening (28 July, Morning: "Believe the Promise")
