Gen 7: Noah and his family in the ark as the flood covered the earth

The flood, resulting in the destruction of the old earth, is like a parallel to the original story of creation. Here, we have Noah, a man righteous before God, as the new Adam.

• v1: Noah painstakingly built the ark in obedience to God, and was saved in it. In the same way, whatever we do in obedience to God will not return void.
• Noah, his wife and children, and their families, was called with him into the ark regardless of their spiritual state: Ham, who proved afterwards to be wicked, was saved in the ark, which intimates, 1) That wicked children often fare the better due to their godly parents, 2) That there is a mixture of bad with good in the best societies on earth. In Noah's family there was a Ham, and in Christ's family there was a Judas. There is no perfect purity on this side of heaven. 3) This call to Noah was a type of the call which the gospel gives to poor sinners. Christ is an ark already prepared, in whom alone we can be safe when death and judgment come.
• v4: God made the world in six days, but he took forty days to destroy it; for he is slow to anger: but, though the destruction came slowly and gradually, it still came effectually
• The world was destroyed once with water, and will be destroyed again with fire (2 Pet 3:5-7)
• v16: God personally shut Noah in. As Noah continually obeyed God, God continually cared for him. The shutting of the door symbolizes a partition between Moses and the rest of the world. Even during the last seven days, the door of the ark was open, and it can perhaps be suggested that anyone who repented and believed might have been welcomed into the ark.
• For Noah to enter the ark, he had to leave his worldly possessions behind and submit to the confinements of being in the ark for a period of time. Hence, as Jesus reminds us in the New Testament, we must leave behind our own sense of righteousness and worldly possessions, whenever these come into conflict with God’s will. Noah submitted to the confinement and inconvenience of being stuck on the ark in order to keep himself alive. This is paralleled in the New Testament, where those who come into Christ to be saved by Him must first deny themselves, both in sufferings and services. Also note that those who by faith come into Christ, will, “by the power of God” (1 Peter 1:5) be shut in, and kept in a stronghold
• Luke 13:22-25: Then Jesus went through the towns and villages, teaching as he made his way to Jerusalem. ²³Someone asked him, "Lord, are only a few people going to be saved?" He said to them, ²⁴"Make every effort to enter through the narrow door, because many, I tell you, will try to enter and will not be able to. ²⁵Once the owner of the house gets up and closes the door, you will stand outside knocking and pleading, 'Sir, open the door for us.'
  "But he will answer, 'I don't know you or where you come from.
• v19-20: Isa 28:17 - water will overflow your hiding place, so that none might escape God's judgement
• v21-23: "Every living thing perished", "everything...that had the breath of life in its nostrils died", "every living thing on the face of the earth was wiped out", makes the emphasis of the destruction of all flesh.
• Isa 10:3 "What will you do on the day of reckoning, when disaster comes from afar?" - those not found in Christ, the ark, will meet certain death when judgement comes.
