Noah's care and diligence in building the ark may be considered, 1. As an effect of his faith in the word of God. God had told him he would shortly drown the world; he believed it, feared the threatened deluge, and, in that fear, prepared the ark. Note, We ought to mix faith with the revelation God has made of his wrath against all ungodliness and unrighteousness of men; the threatenings of the word are not false alarms. Much might have been objected against the credibility of this warning given to Noah. "Who could believe that the wise God, who made the world, should so soon unmake it again, that he who had drawn the waters off the dry land (Gen 1:9, Gen 1:10) should cause them to cover it again? How would this be reconciled with the mercy of God, which is over all his works, especially that the innocent creatures should die for man's sin? Whence could water be had sufficient to deluge the world? And, if it must be so, why should notice be given of it to Noah only?" But Noah's faith triumphed over all these corrupt reasonings. 2. As an act of obedience to the command of God. Had he consulted with flesh and blood, many objections would have been raised against it. To rear a building, such a one as he never saw, so large, and of such exact dimensions, would put him upon a great deal of care, and labour, and expense. It would be a work of time; the vision was for a great while to come. His neighbours would ridicule him for his credulity, and he would be the song of the drunkards; his building would be called Noah's folly. If the worst came to the worst, as we say, each would fare as well as his neighbours. But these, and a thousand such objections, Noah by faith got over. His obedience was ready and resolute: Thus did Noah, willingly and cheerfully, without murmuring and disputing. God says, Do this, and he does it. It was also punctual and persevering: he did all exactly according to the instructions given him, and, having begun to build, did not leave off till he had finished it; so did he, and so must we do. 3. As an instance of wisdom for himself, thus to provide for his own safety. he feared the deluge, and therefore prepared the ark. Note, When God gives warning of approaching judgments, it is our wisdom and duty to provide accordingly. See Exo 9:20, Exo 9:21; Eze 3:18. We must prepare to meet the Lord in his judgments on earth, flee to his name as a strong tower (Pro 18:10), enter into our chambers (Isa 26:20, Isa 26:21), especially prepare to meet him at death and in the judgment of the great day, build upon Christ the Rock (Mat 7:24), go into Christ the Ark. 4. As intended for warning to a careless world; and it was fair warning of the deluge coming. Every blow of his axes and hammers was a call to repentance, a call to them to prepare arks too. But, since by it he could not convince the world, by it he condemned the world, Heb 11:7.
