Exceeding great and precious promises

"If i were dealing with a man's promise, i should carefully consider the ability and the character of the man who had covenanted with me. So with the promise of God; my eye must not be so much fixed upon the greatness of the mercy - that may stagger me; as upon the greatness of the Promiser - that will cheer me. 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 existance. He is a God unchangeable. He has not altered the things 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 withold. 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." - Spurgeon
