For yet seven days, and I will cause it to rain upon the earth forty days and forty nights… -Genesis 7:4

Noah believed what seemed highly improbable, if not absolutely impossible. There was no sea where Noah laid the keel of his ark: I do not even know that there was a river there. He was to prepare a sea-going vessel, and construct it on dry land. How could water be brought there to float it? O mad old man! how canst thou play the fool on so huge a scale as to build a three-decked vessel of vast dimensions where no waters can ever come? Yet he was bidden of the Lord to do it, and he was persuaded that the Lord’s command involved no blunder. The floods would fill the valley, rise up the hills, and prevail above the tops of the mountains.

At times you and I are assailed as to our faith in the Bible, by people who say, “How do you make that out? It is in the Scriptures, certainly, but how do you reconcile it with science?” Let your reply be-We no longer live in the region of argument as to the Word of the Lord; but we dwell in the realm of faith. We are not squabblers, itching to prove our superiority in reasoning, but we are children of light, worshipping our God by bowing our whole minds to the obedience of faith. We would be humble, and learn to believe what we cannot altogether comprehend, and to expect what we should never have looked for, had not the Lord declared it. It is our ambition to be great believers, rather than great thinkers; to be child-like in faith, rather than subtle in intellect. We are sure that God is true! Like Noah, we stagger not at the Word of God, because of evident improbability and apparent impossibility. What the Lord has spoken He is able to make good; and none of His words shall fall to the ground. ~ C.H. Spurgeon
