By faith Noah, being warned of God of things not seen as yet, moved with fear, prepared an ark to the saving of his house; -Hebrews 11:7

The text begins, “By faith Noah.” We shall have to speak about his fear-being “moved by fear”; we shall also remember his obedience, for he “prepared an ark to the saving of his house.” But you must take distinct note that at the back of everything was his faith in God. His faith begat his fear: his faith and his fear produced his obedience. Nothing in Noah is held up before us as an example, but that which grew out of his faith. To begin with, we must look well to our faith. May I pass the question round these galleries, and put it to you also in this vast area? Have you faith? Let each one hear the question in the singular number. “Hast thou faith? Dost thou believe on the Son of God? Art thou resting in the promise of a faithful God?” If not, thou art nothing as to spiritual things. Without faith thou art out of the kingdom of grace, a stranger to the commonwealth of Israel. Thou hast neither part nor lot in this matter if thou hast no faith. But if thou hast even a trembling faith, thou hast the root of the matter within thee. Even if other gracious things be not in thee as yet, they will be ere long produced by faith. Faith is the acorn, from which the oak of holiness will grow. Faith is that handful of corn, the fruit whereof shall shake like Lebanon. Without faith it is impossible to please God, but with faith we become “accepted in the Beloved” (Eph. 1:6). ~ C.H. Spurgeon
