11 As far as God was concerned, the Earth had become a sewer; there was violence everywhere. 12 God took one look and saw how bad it was, everyone corrupt and corrupting - life itself corrupt to the core.
13 God said to Noah, "It's all over. It's the end of the human race. The violence is everywhere; I'm making a clean sweep. 14 "Build yourself a ship from teakwood. Make rooms in it. Coat it with pitch inside and out. 15 Make it 450 feet long, seventy-five feet wide, and forty-five feet high. 16 Build a roof for it and put in a window eighteen inches from the top; put in a door on the side of the ship; and make three decks, lower, middle, and upper. 17 "I'm going to bring a flood on the Earth that will destroy everything alive under Heaven. Total destruction. 18 "But I'm going to establish a covenant with you: You'll board the ship, and your sons, your wife and your sons' wives will come on board with you.

Commentary on Genesis 6:8-11
(Read Genesis 6:8-11)
Noah did not find favour in the eyes of men; they hated and persecuted him, because both by his life and preaching he condemned the world: but he found grace in the eyes of the Lord, and this made him more truly honourable than the men of renown. Let this be our chief desire, let us labour that we may be accepted of him. When the rest of the world was wicked, Noah kept his integrity. God's good-will towards Noah produced this good work in him. He was a just man, that is, justified before God, by faith in the promised Seed. As such he was made holy, and had right principles; and was righteous in his conversation. He was not only honest, but devout; it was his constant care to do the will of God. God looks down upon those with an eye of favour, who sincerely look up to him with an eye of faith. It is easy to be religious when religion is in fashion; but it shows strong faith and resolution, to swim against the stream, and to appear for God when no one else appears for him; Noah did so. All kinds of sin were found among men. They corrupted God's worship. Sin fills the earth with violence, and this fully justified God's resolution to destroy the world. The contagion spread. When wickedness is become general, ruin is not far off; while there is a remnant of praying people in a nation, to empty the measure as it fills, judgments may be long kept off; but when all hands are at work to pull down the fences, by sin, and none stand in the gap to make up the breach, what can be expected but a flood of wrath?
Commentary on Genesis 6:12-21
(Read Genesis 6:12-21)
God told Noah his purpose to destroy the wicked world by water. The secret of the Lord is with them that fear him, Psalm 25:14. It is with all believers, enabling them to understand and apply the declarations and warnings of the written word. God chose to do it by a flood of waters, which should drown the world. As he chooses the rod with which he corrects his children, so he chooses the sword with which he cuts off his enemies. God established his covenant with Noah. This is the first place in the Bible where the word 'covenant' is found; it seems to mean, 1. The covenant of providence; that the course of nature shall be continued to the end of time. 2. The covenant of grace; that God would be a God to Noah, and that out of his seed God would take to himself a people. God directed Noah to make an ark. This ark was like the hulk of a ship, fitted to float upon the waters. It was very large, half the size of St. Paul's cathedral, and would hold more than eighteen of the largest ships now used. God could have secured Noah without putting him to any care, or pains, or trouble; but employed him in making that which was to be the means to preserve him, for the trial of his faith and obedience. Both the providence of God, and the grace of God, own and crown the obedient and diligent. God gave Noah particular orders how to make the ark, which could not therefore but be well fitted for the purpose. God promised Noah that he and his family should be kept alive in the ark. What we do in obedience to God, we and our families are likely to have the benefit of. The piety of parents gets their children good in this life, and furthers them in the way to eternal life, if they improve it.
